Ancestral Context



When researching family history, genealogists put great emphasis on “proof”, and substantiating our conclusions. This establishes a sound basis for objective aspects such as lineage, occupations, residence, etc., but what about the more subjective aspects? For instance, why they moved from A to B, or why so-and-so married so-and-so.

Although good research may yield clues to these questions, we would be much less certain of a conclusion that tried to look into the mind of an ancestor than a conclusion identifying, say, their parentage. Does that mean we shouldn’t be asking those questions? No, of course not, but a focus on rigour and proof may be steering us away from asking them, and so persuading us that we shouldn’t be recording such notions lest they be considered mere guesswork.

Interestingly, academic historians often do dig this deeply and attempt to analyse why things happened the way they did. The point I’m trying to make here is that searching for the context for why certain decisions were taken may not yield anything concrete, but it is still worthwhile as it provides a backdrop for the more substantiated details. As long as we don’t try to elevate such conjecture beyond its supporting evidence, it can help to turn a bunch of disparate facts into a readable narrative. In lucky situations, it may even take you down unanticipated avenues of research and yield something verifiable that might otherwise have been missed.

Every so often, we find an ancestor who travelled far afield instead of remaining in the family village/town. Emigration is a common instance, but my example case for this post involves a 19th Century ancestor who travelled across parts of Britain from Suffolk to Henley, to Kensington, to Burton-on-Trent, and to Derbyshire. I just had to ask myself why.

Henry Woods was born in the small rural Suffolk village of Peasenhall in c1821 to George Woods and Elizabeth Calver[1]. At some point between the baptism of their last child (William, c1827) and the 1841 census, George moved the whole family 150 miles to Remenham Hill in Berkshire, near to Henley-on-Thames[2]. In the 1841 census[3], both Henry and George are ‘Drillmen’, meaning they operated a seed drill for planting seed.

I lived in Suffolk for a while, not far from Peasenhall, and was rather surprised to find an ancestor from that village, let alone from the county of Suffolk. However, I realised how little local knowledge I had when I recently found that Peasenhall was once world-famous for a new generation of seed drills. James Smyth founded a company based on a new lever design in 1800, and this lasted for about 160 years. Before that time, the only drills in use were block drills, in which all the coulters were fixed in one transverse wooden beam. These were “about the most unserviceable instrument of its kind which could be conceived”. The lever drill had each coulter fixed to an independent lever. [4]

In a strange twist of serendipity, I had such a corn drill in one of my outbuildings, here in Ireland. It was constructed in 1887 by R. Hornsby & Son Ltd. of the Spittlegate Iron Works in Grantham, England.

Even stranger is that I also have the remains of a very old block drill. A neighbour once commented that “That’s Stone Age, that is!”.

Remenham was famous for lavender crops:

About a mile and a half N by E. from Henley, in the hundred of Beynhurst, county of Berks, is REMENHAM village and parish, intersected by the river Thames. Park Place, in this parish, was formerly the residence of General Lord Conway: The cultivation and distilling of lavender was established here by this nobleman, and there is still much of this fragrant plant grown in this neighbourhood.[5]

I don’t believe that George and Henry were involved in this since the planting of lavender was quite different from that of corn:

Park Place, near Henley-on-Thames, is celebrated for its lavender plantations which occupy between forty and fifty acres. ‘The plants are raised from cuttings which are slipped off and prepared by women in the autumn, and bedded in, in rows, in any spare piece of garden ground, where they remain for two years. The ground into which they are to be transported, being prepared by shallow trenchings or double ploughing, the plants are placed in rows four feet apart and at least two feet distance in the rows’.[6]

Their seed drills were most likely associated with the planting of corn, which was certainly a product of that region and used for malting[7].

While looking for a connection between Peasenhall and Remenham, I found some tantalising newspaper information. In 1831, a man called Henry Pope was working in Wallingford, just 13 miles west of Remenham, and capitalising on his association with Peasenhall to advertise a new and specialised type of drill:

HENRY POPE, Drill-Man, from Peasenhall, Suffolk, returns his sincere thanks to the Gentlemen and Agriculturists for the great encouragement he has met with since he commenced drilling in the neighbourhood of WALLINGFORD. and begs to inform them he is coming up with A NEW CORN DRILL, so constructed as to sow Clover Seed at the same time the Spring Corn is Drilled, ...[8]

This was not an isolated case of making capital from the association either. In 1839, a Thomas Teago of Peasenhall, “late apprentice in the firm of Smyth & Son”, ran a very similar advertisement:

THOMAS TEAGO begs to return thanks to Agriculturists in General, for the flattering encouragement he has received in the manufacture of his Improved Corn lever Drill, …[9]

By far the most unexpected connection appeared in 1843 in the form of two consecutive advertisements for property sales: one from the Peasenhall area (1000 acres of land for auction in Yoxford and Sibton, including parts of Peasenhall) and one from the Remenham area (Fawley Court Estate. 4000 acres in Henley, Oxfordshire, and Berks, including parts of Remenham). Both of these advertisements were run by the same agents: Messrs Farebrother & Co.[10]

Henry married a Sarah Roomes/Rooms/Roames in Feb 1843 in Henley-on-Thames. Both were recorded as living in Turville, about 8 miles north of Remenham. Sarah’s father, William, was recorded as a ‘Maltster’, and both Henry and his father, George, were now ‘Drill makers’. An interesting observation, here, is that the two witnesses were Charles Woods (Henry’s older brother) and a Sarah Oxlade. Both of these had a marriage of their own recorded in the same register entry, strongly pointing to a double wedding.[11] A clue to how Henry met Sarah can be found in the 1841 census, just two years earlier. Sarah and Henry’s younger brother, John (b. c1826), were both working as ‘Servants’ on the same farm in Cookham, Berkshire.[12]

By the 1851 census, Henry had moved a few miles east to Bisham, but his occupation was now that of a carpenter[13]. My first thought here was that it was something to do with barges since the Thames was an important trade route into London. However, the use of barges was in decline due to the Great Western Railway (GWR), from London to Bristol, being completed in 1841. By 1849, toll income from river traffic below Staines had fallen by 50%, and barge traffic was gradually being replaced by pleasure boats. Henley even got its own GWR branch line in 1857.[14]

Henry’s fourth child, Jane, was born in Kensington, London, in 1853. By the 1861 census, there were four children born in Kensington, and Henry was still a carpenter[15]. Although the River Thames is a dominant feature of London, Kensington would not be well-placed for anything in connection with it. Locating the family in the 1871 census took a little longer than usual as the enumerator must have been in a great hurry — the first initial of each person was used instead of their given names, and all their places of birth were recorded simply as “England” — but it showed that Henry was still in Kensington, and was still a carpenter[16].

Kensington at that time was a mixture of both rich and poor, and there were some awful slums in the area[17]. In trying to determine whether their addresses (see Table 1) were up-market or slum, I found a couple of newspaper references suggesting they weren’t slums: a mention of Francis Henry Tredle, 5 Ernest St, Cam(p)den Hill, Kensington, as “gentleman”[18], and a description of a house on Walmer Rd as “double-fronted house, detached, with large yard and spacious workshops, ... suitable for a Builder's or other manufacturing purposes"[19]. This assessment is confirmed by browsing the Charles Booth survey into life and labour in London (1886-1903). There were also some local breweries, such as the Kensington Park Brewery, Clarendon Rd, Notting Hill, owned by William Lake Woodman and Henry Woodman[20], and this was another possible link with the Henley-on-Thames area.

Henry’s wife, Sarah, died on 4 Sep 1872, aged just 51, of ‘Hemiplegia 5 months, Apoplexy 60 hours’[21]; basically partial paralysis following a stroke. He was remarried within six months but had also moved 130 miles north to Burton-on-Trent. I can understand the need to get away from Kensington, and the memories of a protracted demise, but why Burton-on-Trent? His new wife was Jane Phillips, née Parker (b. c1829 in Bungay). It’s not clear how they met since in 1871 she was running a grocers shop on the Staines Rd, Heston, Hounslow, about 10 miles west of Kensington. It is clear, though, that they had several things in common: both had been recently widowed; both were from villages in the north of Suffolk; Jane’s late husband (William Phillips, b. c1829 in Bungay, d. 1870) was a ‘Master carpenter’ in Brentford, and her father (Robert) was also a carpenter. They were married in Burton on 9 Mar 1873[22].

I know of no family connection with Burton-on-Trent for either of them, or for their former spouses. At that time, Burton was very well known for the brewing of ale, so the above theory may hold some weight. The following (lengthy) transcription is from a trade directory of 1874; the year after they were married:

BURTON-UPON-TRENT. In a broad trough of the Trent valley, in the county of Stafford, surrounded by meadows and bright green islands formed by numerous arms of the river, and standing upon masses and veins of gypsum, triassic rocks, sandstone, and arinaceous limestone, lies the town of Burton. It is 25 miles E. of Stafford, 11 S.E. from Derby, 33 N.E. from Birmingham, and 126 N.W. from London. Burton and pale ale seem to the world synonymous terms, and it will not be deemed amiss to premise our short description with a few broad facts anent the famous liquid staple of the town upon the Trent. Its twenty-seven breweries, belonging to the like number of firms, in addition to malt houses, cooperages, and other erections, cover nearly 300 acres of land. The history of ale brewing in Burton dates back at least to 1295, as in a document of that date yet extant Matilda, daughter of Nicholas de Milindale, leases to the Abbot or convent of Burton certain tenements for "two white loaves from the Monastery, and 11 gallons of Conventual beer, or cider, and one penny; together with seven gallons of beere for the men, and one sextary of hay”, &c. In 1777 Mr. William Bass established the brewery which was the germ of the gigantic business of his grandson Mr. M. T. Bass. At the close of the last century there seems to have been nine brewers only in Burton. Among these appear the names of Michael Bass, William Worthington, and Benjamin Wilson, the daughter of the last named being married to Samuel Allsopp. Mr. Wilson’s brewery, now the old brewery on the east side of High street, was then one of one of the largest in the town. Much of the success of the Burton ale trade was due to the manufacture of a peculiar liquid which was first introduced into the market from this town about 1823, under the name of India or Bombay beer, which then gradually assumed the position long and tenaciously held before by Hodgson’s pale ale.[23]

In 1880, Henry acquired the licence for the Pool Inn, Church Gresley, about 6 miles S.E. of Burton[24]. By this time, he may have been getting a little old for carpentry (59) and this could have been his dream of retirement. When Henry moved to Church Gresley, the youngest children by Sarah (Emma and John) came with them, and also his second son, George Henry. The others remained in Burton-on-Trent. The prior children of his second wife, Jane, remained in the W. London area and never moved north, except for Jane’s grandson, Charles Henry Florence, who is with her in the 1891 census after his mother— also Jane — had died in 1889.

The following table summarises the various locations of the family. I am assuming that Henry was at the same locations for the births of his children.

Henry died 6 Aug 1884 in Church Gresley, aged 62, of ‘Morbus Cordis Syncope'[25] (i.e. a heart attack), and Jane continued to run the Pool Inn until she died in 1894 aged 66.

So, was Henry connected with the brewing trade after switching from seed drills in the Henley-on-Thames area? A barrel or cask maker would have been described as a “cooper” so there’s not much evidence for that. How much richer is the picture, though, when it includes some context rather than a mere list of facts such as those in Table 1?

Supporting a Proof Standard



Should our computer software support a single standard of genealogical proof, and if so then should it be part of the data that we share?


The question of whether a genealogical data model should support a single standard of proof came up recently on the RootsDev developer group, and the consensus was ‘No’. This may come as a shock to some people but bear with me while we examine the context more deeply.

The Genealogical Proof Standard (GPS) is held in high regard amongst genealogists, not just as a standard of professionalism but also as evidence of their credibility in academic circles. It would therefore seem reasonable to expect software to support it, and this has certainly been recommended before[1]. The crux of the issue is not that software shouldn’t support it, but that it should not involve a mandatory and standardised representation in a data model designed for sharing.

Although I’m not aware of any alternatives to GPS in the field of genealogy, other fields do have their own “standards” of proof. This obviously includes mathematics, but other investigative fields, too, such as CSI, archaeology, and heir hunting. Whether this is significant to us is debatable, but what is clearly significant is that the application of the GPS is not prescribed by the standard itself. What I mean by that is that the process by which a user addresses the requirements of the GPS — the five elements — and how it keeps track of their evidence and its applicability, would be done differently by different products. An entry-level product may take a very literal approach which could result in it appearing more laborious, but a sophisticated product could make it more palatable through better insight and visualisation. This has to be the prerogative of the product designer, and any attempt to impose a straightjacket through standardisation would be the death of that standard.

Indeed, a product may not be concerned with the GPS at all if the context is inappropriate, or if the commerciality would be in doubt. While we can recommend the GPS, and encourage it through training and qualifications, a heavyweight product may not have the mass-market appeal to make it viable.

I briefly covered this topic in some of my early thoughts on standardisation at: Musings on Standardisation, but my lack of clarity there caused at least one serious rift between a colleague and me. The difference, you see, is that those thoughts, and those in the recent RootsDev thread, are talking about the data model used to exchange data, and not about the software products that we use. I’ve just explained why the designers and vendors of software must be given free-rein to innovate as they choose. The data that those products share may or may-not include the meta-data associated with a particular research process.

Now this is going to raise a whole bunch of questions and potential responses so let me just recap on things. Our core data will involve both evidence and conclusions, and so it must indicate how they relate to each other — independently of the research process used by the creator. Any data used to support a specific research process is technically meta-data because it’s an aid to the research rather than a product of the research. It doesn’t matter whether we consider our data to be lineage-linked, evidence-based, event-based, or all of the above (as I do).

So what impact does this have a standardised data model used for exchange? In computer programming, there is a pragma concept which involves additional statements being associated with the computer code. These statements are designed purely to direct a software program how to process the computer code. They are not part of the code’s language, or its grammar, and those pragma statements are specific to different programs. This situation is actually quite similar to the genealogical case since the core data is independent of such meta-data, being quite valid without it, and that meta-data would be specific to a given product. If the two contributions are distinct then we have the potential benefits of both worlds. We can share our core data (including lineage, events, places, sources, transcriptions, attachments, etc) with anyone, and optionally share our additional research status with someone using the same product.



So is this possible? In fact, it is quite easy since the XML data syntax routinely uses XML namespaces to differentiate different grammars in the same data contribution. Although I tried to give an introduction to the benefits of this feature in Digital Freedom, it’s still quite technical. You might imagine it as a foreign-language annotation that someone has added to someone else’s text in order to explain the context of selected words and phrases. You could share the combined work with someone, or filter out the foreign annotation and leave the original work. Although this namespace concept is mostly associated with XML, it is actually something that could be employed with any data syntax, if necessary, including a GEDCOM-like one.

Revisiting the Family Group



In a previous post about genealogical data, I described a generic Group entity designed to model the many varieties of a Family Unit, and more besides. I am now undoing its implementation and re-crafting the Group so that it becomes one of the most fundamental data entities in the recording of history.

In Family Units, after denigrating the precise definition of a ‘family’, and any possibility that we could objectively identify one through records, I described a generic implementation that could mean whatever you wanted it to. This followed in the footsteps of the GENTECH project which took a similar generic stance[1]. The main difference in my implementation was the use of Set-operations to group people together, and to derive one Set from another.

As a very brief example of how this worked, consider a marriage of two people, both of whom had been previously married and who bring associated children into the new marriage. We would therefore have multiple contributions to the new ‘extended family’, including the conjugal children and two sets of stepchildren.


The idea being that once the three groups of children have each been defined then the extended family is easy to define since it is simply the Set-wise union of those and the two parents. The implementation even addressed the thorny issue of time-dependent membership of a group. For instance, once a child gets married then they’re typically viewed as part of a separate family unit, and so they’d leave one Set and enter another.

One problem with this general approach is that it’s very people-focused, and that means it is most useful for categorising people. This is not bad, but it’s certainly not the whole story either. Anyone studying history, including genealogy and family history, will appreciate that an organised real-world entity such as a company has a history, or “life”, of its own.

Although I never used these Groups for representing family units, I did intend for them to be used to model things such as military units, societies, clubs, etc. It didn’t take long before I realised that my hasty implementation wasn’t enough. The corresponding Groups would have to share a lot in common with both Persons and Places; a pattern I’d already capitalised on in their case.

So what was missing? In STEMMA® V2.0, Groups only had a title, a type, and a time-dependent Set of Persons. The following features were also required but were only supported by Person and Place entities:

  • Alternative names, variant spellings, and name changes. Persons and Places already shared a common implementation for this.
  • Parentage. Being affiliated to a bigger Group, as opposed to being a subset of some other Group.
  • Requirement to be associated with Events, and hence to cite supporting sources for that Event, and identify extracted and summarised items of information (aka ‘Properties’) relevant to the Group.
  • Ability to reference resources such as images, photographs, documents, etc., applicable directly to the Group.
  • How to deal with Groups being split or merged during their history. This is already a problem for Places, and my eventual solution should apply to Groups too.

The next release of the STEMMA specification (V2.2) will incorporate all this functionality but, surprisingly, it streamlines things rather than complicates them. Software engineers will understand when I say that it allows me to share certain base classes in the implementation. Effectively, Groups then become a top-level entity in the specification, alongside Person, Place, and Event.

As a real example from my own data, anyone who read A Grave Too Far may remember that it mentioned a British cavalry regiment that one of my ancestors served in: 14th/20th Hussars. This regiment was created through the merger of the 14th King's Hussars and the 20th Hussars in 1922. The honorific "King's" was added back into the title in 1936. This short description already involves a merger, a rename, and corresponding events. I associate historical sources with this regiment-type Group, including the relevant Wikipedia page: 14th/20th_King's_Hussars. My blog-post also cited a newspaper reference to the movements of the regiment: “Cavalry Change at Risalpur” (footnote 6). This was particularly interesting because it was relevant to the life of my ancestor, and yet that reference only described the movement of the regiment and not of any specific people. However, the data relationship between the information source, the Event, and the Group, was identical to a similar situation involving the movement of some individual.

As explained in Evidence and Where to Stick It, events are an anchor point for declaring supporting sources. They are effectively a snapshot of history from which we can derive our evidence, and virtually all sources are relevant to some primary event. The situation, here, is the same for people as for groups.

The duality of persons and groups has already been explored by Ronald L. Breiger, of Harvard University, in the context of empirical analysis of interconnected groups and people[2]. In the context of micro-history, the benefit is two-fold since the relationship of people to groups can be modelled but also the groups themselves, independently of people. The latter is important for anyone studying the history of an organisation, military units, colleges, universities, etc. For too long, this type of research has been neglected from a software point of view, and not considered in relation to genealogy or family history, even though the standards for research should be the same, and many of us have already ventured into such territory.
