(Repeating from Facebook and adding comments) I did this the other day and immediately got about 160 autosomal "matches" in the Geni tree. (Now more than 190) Two of them were with people I already knew were related to me: Of two possible 1st cousins twice removed, one is actually my 3rd cousin; the other is my 3rd cousin once removed.
Maybe the matching algorithm sets the bar way too low?
I ran "You are connect to . . ." for several putative cousins ranging from 2nd cousin twice removed to 3rd cousin with at least 100 overlapping cM. Geni showed them to be related through two to four or more marriages. Yes, perhaps there is also a blood relationship we haven't discovered, but I am dubious.
And what am I to make of a suggested 2nd cousin twice removed with an overlap of just 23 cM, the longest segment being 9 cM? I'm sticking with my 100 cM minimum interest level.
A lot of Ashkenazi noise, I think. Maybe I'll take a look at some with a longest overlapping segment of 13 or more. I've done that with several profiles; all were related to me through multiple marriages.
