Here is an interesting instance of autosomal DNA triangulation that (I believe) could point me to a Jones ancestor of mine who is currently "just behind a brick wall". I have drawn up a "map" of a large triangulated segment on chromosome 2 that is shared among 4 descendants of A.B. Jones (1836-1902) and Mary Coates (1839-1893) and 4 descendants of Adam Shriver (1736-1815) and Christina Strosnider (1740-1803). 7 of these testers match one another on the same segment of chromosome 2 - between 22 cM-58.5 cM. One of the testers has not submitted to Gedmatch, but she matches all 7 of the other tests on Ancestry DNA. Here is an image of the map if you would like to see more on this:
I am inferring that this could be a match through A.B. Jones's father - John H. Jones - who is listed in several records as having been born in "Virginia" in 1806:
First - Adam Shriver and Christina Strosnider and their children lived in Greene County, Pennsylvania and Monongalia County, Virginia from the 1760s on, which is an interesting possibility for "Virginia" in 1806.
Second - the family of A.B. Jones's mother, Elizabeth Ballou (1806-1904) came from Massachusetts and Rhode Island going back several generations. As such, it is hard to imagine her having a connection to the Shrivers:
Third - Mary Coates's father, John J. Coates (1815-1867) appears to have been born in Ohio or Kentucky. While it wouldn't shock me to find a family connection here, it seems as if this would have been prior to Adam Shriver and Christina Strosnider:
Fourth - Mary Coates's mother, Eliza Wright (1820 - ?) is listed as having been born in Kentucky. Her 1880 census record lists that her father was born in Kentucky and her mother was born in Germany. A Shriver connection to Eliza Wright seems unlikely:
The big challenge that I now face is trying to figure out a possible connection between the children of Adam Shriver and Christina Strosnider and the birth of John H. Jones in 1806. From a DNA perspective, I can't help but notice the large segments that my Jones relatives each have in common with Roger and GAR - the two descendants of John George Shriver (1763-1831). This would seem to suggest that one of John's children could fit as one of the parents of my John H. Jones. Looking at his children though, I'm just not seeing an obvious candidate: https://www.wikitree.com/wiki/Shriver-35
Stepping back to the children of Adam Shriver and Christina Strosnider. Again - there is no obvious candidate jumping out here: https://www.wikitree.com/wiki/Shriver-34
Any thoughts would be appreciated. This is one of the most promising autosomal DNA matches that I have come across yet.
Thanks to Jackie King for all of the excellent work she has done documenting the family of Adam Shriver and Christina Strosnider. The profiles you created for the family have been very helpful as I try and sort through this.
