Can someone please explain to me how cousins work? First, second, third cousins? Removed cousins? Twice removed cousins?

Question

I tried to Google it but it got VERY confusing very fast, if anyone could dumb it down for me that would be great lol

Answer 1

Two of my sisters married men who are first cousins.

Each sister’s children are first cousins of the other sister’s children through their mothers.

Each sister’s children are second cousins of the other sister’s children through their fathers.

Each sister’s children are first cousins *once removed* of their cousins’ father.

Each sister’s children are nephews/nieces of the other sister.

Each sister’s children are nephews/nieces *by marriage* of the other sister’s husband.

Confused yet? 😂 It’s true, though.
