uh-oh.. a different story

I wouldn't be too quick to assume infidelity (I know you didn't say anything about that specifically).

It is possible that occurred, of course, but it is also possible there was an adoption or some other similar explanation for your cousin's mismatch.

Informal adoption (in the 1870's ) is a possibility - his grandfather is 10 years younger than my great-grandfather.

He's about my age and our mothers were both pregnant that year (and I always that that I was the one went home with the wrong family )

I invited a cousin to join the project so we could profile our branch of the family. I match other family members 36/37 and 34/37 at 10 and 11 generations back. A genetic difference of 15 on the 37 marker test. There's 0% chance the grandson of my great-grandfather's brother and I are related.
