Which one is my second cousin once removed?

If you have ever wondered how your relations are able to rank the extended family as “once removed”, “second cousin” and so on, well here is a handy graph from Wikimedia which should clear things up. It shows an extended family tree back to great great grandparents and down as far as the third cousin twice removed. Might be handy to resolve those arguments about whether Auntie Ethel’s offspring are “once removed” or just “should be removed”.
