What's the difference between a cousin a second cousin and a cousin once removed

Question:

What's the difference between a cousin a second cousin and a cousin once removed?

Best Answer - Chosen by Asker: A good way to remember 1st, 2nd, and 3rd cousins is:
If your common ancestor is a set of grandparents than you are first cousins.
If your common ancestor is a set of great grandparents than you are second cousins
If your common ancestor is a set of great great grandparents than you are third cousins, etc.

The once removed stuff is where it gets tricky for some people. Once removed means that they are one generation removed from the degree of cousin you are talking about. The generations are "uneven" so to speak. A first cousin once removed is NOT the same as a second cousin. For instance, if your first cousin had a baby, the baby would be your first cousin once removed. If you had a baby also, it would be second cousins with your cousins baby (because their common ancestors are a set of great grandparents) , but would again be first cousin once removed to your cousin.
