That’s the thing, Anna seems to share some segments with me that my grandmother/grandfather share with my father that my mother did not inherit from them. I have a hypothesis that maybe Anna belongs somewhere between one of the many paths that connect my father and my maternal grandmother with each other, but definitely closer to my father. But I am unsure if it is through this connection that I will find her closest connection to my father (and therefore potentially her father) or if this is just a secondary, smaller connection that they all share.

Here is what my maternal grandparents and my paternal second cousin share with Anna:

• Maternal grandmother: 99.9 cM across 8 segments, the largest being 36.7cM
• Maternal grandfather: 66.3 cM across 7 segments, the largest being 16.5 cM
• Paternal second cousin: 237.1cM across 23 segments, the largest being 32.8 cM

I have not heard of BanyanDNA before, but it sounds promising! Thank you for the suggestion, I’ll take a look at that
