I manage my father's Ancestry DNA profile, it's got the usual 4th/5th/6th cousins spread all over the world.
Recently I got a hit on a "Distant Relative" (14cm) in the US who has the same surname, I found them on facebook, made contact & we exchanged a few details.
Turns out they're the grandchildren of my grandfather's brother (my second cousins I think). There'd been some split in the family before my father was born & he buggered off to the US never spoken of again.
His son (Irish born but now deceased), should be my father's first cousin & these children of (American born), would be his first cousins 1x removed or second cousins, right? However the CM should be much higher & it should display at a closer relationship than distant relative, correct?
14cm is something like fourth cousin 2x removed sharing a great great great grandparent. Given the isolated island population of Ireland around that period, I suspect now that gramps & granny (both long passed), may have held a tightly guarded family secret.
Any thoughts? Is Ancestry's algorithm total bull or is there more at play here?
