Mystery match, does not know father. Matches me on mother's paternal side.
Me and match: 376.3 cM,15 matching segments, largest segment 47.2cM
Me and his daughter: 84.7cM, 4 matching segments, largest segment 30.0cM
My mother and him: 824.7cM, 24 matching segments, largest 93.5cm
My mother and his daughter: 333.5cM, 12 matching segments, largest 63.1cM
All are Ashkenazi Jewish, mystery cousin and I are half, my mother 100% and his daughter is 18% or something like that.
We also have more shared DNA, with my great grandfather (J) and his brother (J) married H and her sister R. So if he is a 2C1R, then his grandmother would be R, which is my great grandmothers sister.
Very confused because of endogamy. I'm wondering if this match could be a double 2C1R, or triple?
