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

siblings – share parents

first cousins – share grandparents

second cousins – share great grandparents

third cousins – share great great grandparents.

Removed is generational. So if A and B are first cousins, A’s children are first cousins once removed to B. A’s children and B’s children are second cousins (as above) to each other.

A’s grandchildren are first cousins twice removed to B.
