Have you ever been to a family reunion and had to ask someone how the two of you were related? Family ties can get pretty complicated. This quiz is going to test your knowledge of the family tree. I'll give you a relative, and you'll have to indicate what there relationship to you is. Because this stuff can get pretty confusing, I've provided a basic explanation below. Good luck!

If you're unsure how to trace back the family tree, here's an explanation! Basically, the number in "second" or "third" cousin tells you how far back your shared ancestor is. First cousins share grandparents, second cousins share great-grandparents, third cousins share great-great-grandparents, and so on. "Removed" means you're in different generations. Your mom's first cousin is your first cousin once removed, because the two of you are a generation apart. Still confused? This article explains it a lot better than I do.
