Oh and in this case, it was https://www.geni.com/people/John-Brockett-The-Immigrant/6000000009957728134 who brought THIS dna strand to me in America from Mackrey End, Wheathampsted Parish, Hertfordshire, England.
I think it can but only if it’s combined with lots and lots of family trees, which I think they’ve been doing.I think ethnicity estimates can be way off base (using percentages of probabilities) but if you share a small fragment with someone who is FAR away from you genetically , that makes a big triangle. It’s got a long base. So your connection as cousins will be many generations back.But, if you BOTH did extensive family trees, they’ll connect. I’m absolutely floored at how well this is working.
We might not have any shared segments but still be cousins. If we have different parts of the original DNA, they won’t line up today but as we get closer together up the trees, more and more “parts of the original” would show up.
really? I know so little about the part of my ancestry. Hard to trace. I could only get back to 1880s or so.I changed the resolution down to 1 and we match
Largest segment = 6.3 cM
Total Half-Match segments (HIR) = 22.2 cM (0.620 Pct)
5 shared segments found for this comparison.
chr 3, 5, 6, 18, 19
What I’m doing is “spot checking” cousins, jumping around to find commonalities. So if it shows we are 15th cousins and you’re H1b1-T16362C, I start going to other H1b1-T16362C that are on geni and look for family tree connections in common.
It’s been hooking together really nicely. this is all following the Rogers / Luster line that was mostly in Connecticut, NY and NJ, but it’s got hooks everywhere from spreading so far.
