A third Cavers branch matching in Y-DNA project results

I’ve blogged before about the Cavers Y-DNA project at Family Tree DNA. In November 2013 I blogged about preliminary results, including for two different Cavers branches. Now we have the results for a total of three different Cavers branches, and I can reveal those here.

These results are all from the Y-DNA for male line Cavers descendants. Y-DNA is passed down from father to son, generation after generation. This means that a modern-day male descendant should have inherited the Y-DNA from his distant male line ancestors. And if his family name i.e. surname is passed down from father to son over many generations, with no female illegitimacy links in the chain, this should be a guide to his distant ancestry in that surname line. And that includes Cavers.

We now have three Cavers lines represented in the results for the Cavers Y-DNA study. And as before I’m going to spell out the ancestral lines represented by each of the volunteers who has been DNA tested.

Volunteer 1 is descended from the mysterious Walter Cavers who was born in Roxburghshire circa 1795, before migrating to Nottingham in England, and having many living descendants.

Volunteer 2 descends from Thomas Cavers (ca1810-1879) who emigrated from Castleton, Roxburghshire to Lanark County, Ontario, Canada. This Cavers family can be traced back one further generation, to John Cavers and Jean Douglas, who married in Hawick in 1789 and lived in Castleton. But beyond that it is a mystery.

The new volunteer 3 descends from John Cavers and Margaret Cleghorn. This John was a son of John Cavers and Elizabeth Hislop who I have blogged in detail about before. Again this is a Roxburghshire family, and traces back to a couple who married in Hawick in 1793.

I am pleased to say that Y-DNA results for all three of these Cavers branches match, suggesting that all three branches have a shared origin further back in time. In other words these lines and their descendants are cousins of each other. There are a few small differences between the DNA results, but not enough to prevent a confident match being made. It is normal for some mutations in DNA to occur over many generations.

In addition in the project we have a couple of non-Cavers descendants (at least as far as we know) who have been Y-DNA tested and seem, intriguingly, to be pretty close matches to the Cavers results. Not sure what is happening there – it’s a mystery! But the more Cavers people we can get tested in future, the clearer the picture could become.

What I would really like to see is for more different Cavers branches to be tested. For example we haven’t yet had anyone volunteer to be tested from the extensive Berwickshire Cavers family, or the Cavers family including Adam Cavers and his many descendants and cousins, including a large number who settled in Ormstown, Quebec, Canada. Nor have I yet been able to identify a male line Y-DNA carrying living descendant of my own Cavers branch.

Basically the more Cavers branches we can get tested, the clearer the picture will become of how they are connected to each other. There will almost certainly be some Cavers Y-DNA results that don’t match others, but that in itself is useful information, and worth knowing.

So if you are a male line Cavers descendant who may carry Cavers Y-DNA, especially for a so far untested branch, I would love to hear from you. Or if you are a female Cavers descendant but have a brother or uncle or cousin who may be able to be Y-DNA tested for your branch then that would be great too. I can’t afford to pay for all tests, but have recommended before that cousins can club together to spread the cost of a DNA test. And DNA tests are now at a lower general cost than they have ever been. For more information on the testing process, see my earlier blog post about the project.

I will continue to report new results as they come in.

Preliminary Cavers Y-DNA project results

Some months ago I started a Cavers Y-DNA project at Family Tree DNA. This is very much a long term thing, as I blogged at the time. The aim is to compare direct male line Cavers DNA, passed down from father to son, to see if different Cavers lines are related, and how closely.

So far one male line Cavers descendant has signed up for a brand new Family Tree DNA test. He descends from a branch of Cavers that is believed to originate in Roxburghshire, Scotland, with Walter Cavers born in Scotland circa 1795, but who then moved to Nottingham, England, and established a large family with many descendants. Walter’s origins are something of a mystery. There is no obviously clear baptism to tie up to him, without some problems and question marks. And many Cavers births are missing from the parish registers anyway. His could be one of those. So let’s call for the purposes of this blog post this DNA line that’s been tested Volunteer 1, a direct male line descendant of the mysterious Walter.

Shortly after that another Cavers descendant agreed to transfer their Y-DNA test results from Ancestry to Family Tree DNA. This can be done for a small fee, and is possible because of an agreement between the lab that Ancestry use and the Family Tree DNA system. This person descends from Thomas Cavers (ca1810-1879) who emigrated from Castleton, Roxburghshire to Lanark County, Ontario, Canada. He had many descendants, and a number of siblings who emigrated around the same time. This family line can be traced back to Thomas’s father John Cavers, who married in Hawick in 1798, and had a large family in Castleton parish. But John’s origins are also something of a mystery. Again there is no obvious baptism for him. Nor do the names of his children offer significant clues. Let’s call the DNA testee in this line Volunteer 2, again a direct male line Cavers descendant, this time of Thomas and John.

Some of the DNA results for Volunteer 1 came through quickly, for 12 markers of Y-DNA, and showed a perfect match with Volunteer 2’s Y-DNA. For such an unusual surname this suggests strongly that they have a shared male ancestry, although because Volunteer 2’s DNA was transferred over from Ancestry it’s not possible in Family Tree DNA to run a further report estimating how close the connection is. Then tonight the fuller results for Volunteer 1 have come through, sooner than expected, accurate to 37 markers, which can be compared with the 27 markers available from Volunteer 2’s transfer from Ancestry. And again they match very very closely. There is one genetic difference, but that may be due to a mutation in a later generation. Again though the indication is shared ancestry.

But to complicate things further a third test kit then matched the Y-DNA of volunteers 1 and 2, and this person isn’t even a known Cavers descendant! They are a Cowings, descended from Cowings or Cowan ancestors traced back to Gateshead, County Durham, and 1720. On 12 markers this person, let’s call them Volunteer 3, for they have now joined the Cavers Y-DNA project, match the DNA results for Volunteer 1 and Volunteer 2 perfectly. Extending things to 25 markers Volunteer 3 has a close match to Volunteer 1, with just 2 genetic differences i.e. a genetic distance of 2, and an even closer match to Volunteer 2 (at least those 23 markers available after transfer for Volunteer 2), with 1 genetic distance. At 37 markers Volunteer 1 again matches Volunteer 3 closely, with a genetic distance (differences in marker numbers) of just 2 – very strongly indicative of shared ancestry. Volunteer 2’s available 27 markers match Volunteer 3’s, but with a genetic distance of 3 this time. A further 3 genetic markers (outside the core 37) available for Volunteer 2 also match Volunteer 3’s results.

So what does this mean?! Well I think the 12 marker results indicate shared male line ancestry in all cases, but the higher genetic distance when more markers are compared suggest it is somewhat distant. Genetic distance grows as mutations in the DNA occur, and these mutations happen more frequently over a long time, and many generations. Volunteer 1’s line seems to tie up more closely with Volunteer 3’s line than Volunteer 2’s does. But I am confident that they ultimately have the same ancestry. With the Y-DNA results from Volunteer 1 and Volunteer 3 it’s possible to run a report at Family Tree DNA which estimates how closely the lines are related. This suggests that the chances of Volunteer 1 and Volunteer 3 sharing a common ancestor in 6 generations is almost 54%, in 8 generations 71%, and in 10 generations 83%. In genealogical terms this is relatively close, and quite exciting.

As for the Cowings/Cowan thing, I can’t give a simple answer at the moment. One possible explanation is that a distant Cowings or Cowan ancestor dallied with a Cavers, to put it nicely! Or that there is an illegitimacy link there somewhere, and a Miss Cowan had an illegitimate child, father someone Cavers, and the child took on the Cowan surname. There was a cluster of Cavers people in the Durham area from at least the 18th century onwards, and possibly earlier. Though they probably had Roxburghshire origins ultimately.

Alternatively it’s possible these Cavers lines link up to a Cowan in their ancestry somewhere. That is equally possible, and DNA can’t give a simple answer to this, especially because anything like this probably happened an extremely long time ago, before the good written records we genealogists rely on for piecing together family trees using documentation.

But it is all very exciting. To have two separate Cavers lines link up through the DNA when there was no evidence before of a connection is superb. We can now reasonably say that the Nottingham descendants and the Canadian descendants of John Cavers in Castleton are distant cousins of each other. And the Cowan matching side of things is interesting for raising more questions than answers. All information is good information.

Ultimately though we need more volunteers to sign up to have their DNA tested, from different Cavers branches. The more lines we can get tested, the bigger the picture the DNA can build of if and how the various lines are connected. And perhaps we might in some cases be able to back this up by tracing links in the documentary records, spurred on by the findings from the DNA tests. That would be nice.
