What do you call the son of your mom’s cousin?

I don't know about you but I get a headache trying to figure out the proper term for how distantly related people are related. Lifehacker tells us that Wolfram Alpha does all the heavy lifting for you:

From Lifehacker:

What do you call the son of your mom's cousin? How about the husband of your mother's uncle's daughter? 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.

More detail is available at the Wolfram Blog article, My Cousin’s Cousin’s Niece’s Grandfather Said to Just Ask Wolfram|Alpha.

  1. I don’t think that graph is correct. I thought that your cousin’s child is your second cousin and your parents’ cousins children are ‘1st cousins twice removed’??
