But sometimes those large segments may be passed down for many generations. Several of my kits--all related on my maternal grandmother's side--share the same large segments with several kits administered by a man named Luc.
|Luc's Tested Family Members--With DNA Shared With My Relatives|
Luc's tested first cousins on his maternal side all (but one) share a segment of 20cM or more on chromosome 2 with several members of my family including my great aunt, mother, and uncle. Some of them share reasonably large segments with my cousin Judith on chromosome 8 (Judith and my mother are second cousins; my mother and Ron are third cousins.)
So this looks quite promising in some kind of connection between my maternal grandmother's family and Luc's mother's family. But here's the issue: I have my maternal grandmother's family well-documented in what is now Subcarpathian Ukraine back to the late 1700s. Luc has his mother's family well-documented in what is now the Botosani, Romania area back to around 1850 for sure. He explains that "unfortunately there are no civil vital records before 1865. So I know for certain the births of a lot of relatives but the death certificates for older people are not reliable as far as the place of origin. There are some scattered community records for 1850s and some census-type data for foreign subjects for 1825, 1834 and 1844."
So it seems like we can't be related any more closely than 6th cousins--but that one segment has been consistently passed down for many generations!
|Kolodne & Botosani are 145 miles apart, separated by a mountain range. Google Maps says it is a 7.5-hour drive.|
Using GedMatch's Matching Segment Search doesn't show this to be a very common segment. Besides several of my kits and several of Luc's, looking at people sharing segments of 18cM and more, there are kits administered by two other individuals--each with two kits sharing this segment. For the first, the relatives with this segment had ancestors from Soroca (on the modern-day Moldova/Ukraine border) and Illintsi (near Vinnitsa, Ukraine). For the second, I match her and her father--and his parents are from Berdichev, Ukraine.
|Origins for Individuals with this Segment|
As another data point, Luc and I share an mtDNA haplogroup--however K1a1b1a is a very common Jewish haplogroup. So it may mean something, or it may mean nothing at all.
So what's with this segment--and why does my Subcarpathian family share it with these families? I know via DNA matches (stronger ones than with Luc & his family) that my grandmother's parents are who I think they are--and they were both born in Subcarpathian Ukraine. Could there be two or more much smaller adjacent segments? Could this be a sticky segment which was simply passed down intact for many generations through descendants of four siblings/cousins who ended up geographically separated? Something else? I'd appreciate any ideas.
So now the question is how old this segment actually is!
