We are searching for my husband's father with nothing more than a name.
We did DNA through Ancestry and the person we thought would be his half-sister Person 1 came back as his first cousin 1,187 centimorgans shared across 43 DNA segments.
He also matched with a second cousin Person 2 292 centimorgans shared across 13 DNA segments. Person 2 matched Person 1 as 3rd cousin 129 centimorgan shared across 9 DNA segments.
What we know is Person 1's father who we thought was Person 3 father is cousin to Person 2's mother. Father and Mother both deceased were first cousins.
Trying to understand something that I know nothing about.
Is it possible Person 1 is Person 3's half sister?
