Can anyone help explain this UK connection to Appalachia/Upper South
Pretty much, my mum and I have both done a DNA test, and to my knowledge, we are your typical people of rural to town British Isles stock going back multiple generations. However, when I was looking through my DNA matches, I was consistently seeing matches from this mid 1840s to 1860s couple from Rutherford, North Carolina, who were around Spartanburg, South Carolina, and that sort of border area between the two states. I was born in the early 2000s, for context, when it comes to placing the matches.
I proceeded to look at the parents and grandparents of this couple, and I saw that I also had unique DNA matches with all the different lines this couple descended from, such as their grandparents who were born in the late 1700s. Most of them seem to follow a Russell, Virginia, Amelia, Virginia, or Mecklenburg, Virginia, to North Carolina and South Carolina type of path, and I had matches through every line.
For fun, I did some research into this couple and their line for a bit, and I added them as ancestors to see how many matches I had. In total, through this mid 1850s couple, I have over 40 matches through this random couple alone, with a large amount appearing through ThruLines. Looking at the shared matches page, there are definitely quite a few more who just have not built a tree, or whom I cannot link yet.
It is such a range of matches. They are all in the 8 to 50 cM range. Annoyingly enough, the ones with less tree information are usually the higher matches. Usually, they average out at about 30 cM or so. They all descend from this couple, who had children from the 1850s to the 1890s. With the grandparents of this 1800s couple, I usually share about 10 to 20 cM, but with the 1700s ancestors, it is much harder to place them.
There is one match in particular with whom I share three segments, and they share three of the grandparents of that 1800s couple, which fits with me sharing all three of those segments.
I was wondering whether this is typical for someone from the UK to experience, perhaps due to colonial settler endogamy, or whether the particular numbers and situation of matching a wide variety of lines, including all the ancestral lines of this mid 1800s couple, is more unusual. I find it very interesting and quite random.
I can answer any more questions if needed, but I find it quite interesting how randomly connected I am to this family.
