Relationships to parents

Question

If my mother and Father are 2nd Cousin, are there Children 3rd cousin to them?

Comments

The children of your mother and father would be sons and daughters.  My understanding is the children of your grandparents are aunts and uncles making their children 1st cousins.  The children of your great grand parents are great aunts and uncles and their children are 2nd cousins.  The children of your 1st cousins would become 1st cousins once removed but often mistakenly refered to as 2nd cousins.  You would then be dau to your parents.  to their 1st cousin you would be 1st cousin 3 times removed

Answer 1

You may get conflicting answers, but, in general:

If A and B are 2nd cousins, the children of A are 2nd-cousins-once-removed to B (and vice-versa). The children of A are 3rd cousins to the children of B.

I'm really not sure that applies to children of married 2nd cousins. That would imply each child is a 3rd cousin to their siblings.

EDIT: Third cousins are both 3 generations removed from siblings. The once-removed implies an unequal number of generations removed. E.g., for 2nd-cousins-once-removed, one of them is 2 generations removed, the other is 3 generations removed  (from siblings.)

Comments

So that would make me a 2nd cousin once removed to my mother and father, and a third cousin to my brothers and sister!

So it would seem, Richard! I suppose you could say your closest relative is a 2nd-cousin-once-removed (if your parents are alive), or "some 3rd cousins," otherwise.
