I think 13.1cM as the longest block is pretty distant but it's doable with the total of 31cM. I had someone about that amount and traced a lot of her ancestors and wasn't able to find a connection. But from someone else who had ties to the same town as this person and my paternal grandmother, we shared 52cM, and I traced his ancestors too. Although predicted 3rd - 4th cousins, I found that we were 5th cousins but noticed in the process a surname that appears on my tree. So we're related two ways, but was unable to verify that 2nd connection.
So this may be the case for you. But you listed that Woman's name, seems german "von", not sure if that's her married name or not. Could be IBS thru Flemish (van). But it's hard. The best way to figure these out is triangulation. Even that I'm still a novice a, but learning fast. :) K On Friday, August 8, 2014 1:09:30 PM UTC-7, Doug da Rocha Holmes wrote: > > Nice info, Kalani. > > There is a person in my Family Finder matches who must be one of these IBS > links.
