Type how you're related into Wolfram Alpha's computation engine, and it returns the relationship—first cousin once removed, in that last example. Not only do you get a sketch of the family tree when you enter something like "great-uncle's son's daughter," but you get a quick chart explaining just how related you are to the person you're describing, in a "blood relationship fraction." You may now proceed to whittle down your holiday card list, as well as impress everyone with your proper genealogical naming at the family reunion.
