Question:

2nd cousin vs cousin once removed.?

2nd, 3rd, 4th (etc) cousin vs cousin once, twice, three times (etc) removed? I've always been confused about this....
Please explain and give me some examples.


Best Answer - Chosen by Asker: I think the easiest wat to remember all of that is as follows:

-If you share a grandparent with someone, you are first cousins
-If you share a great grandparent with someone, then you are second cousins.
-If you share a great great grandparent with someone, then you are third cousins
_If you share a third great grandparent with someone, then you are fourth cousins
etc....

The once removed stuff comes in when you are talking about a cousin with a varying degree of relationship to the common ancestor than you. For example, if we are talking about the relationship between you and your cousins child. For you your common ancestor is your grandmother, for the child, your common ancestor is their great grandmother. The difference between a grandmother and a great grandmother is one generation making your cousins child your first cousin once removed. If you and your cousin each had a child, their common ancestor is their great grandmother which we've already discussed is second cousins.

There is a really neat relationship chart that serves as a great visual at

If you are anything like me, a visual always helps. Blessings.
