Have I mentioned this? I was traversing through a family tree linked to mine via marriage, when I discovered one of the descendants in that tree was a first cousin of mine, via my direct line. So I was related to him, and his entire family of course, twice. He is my first cousin, so one of his parents is a sibling to one of mine, but he is also my 4th cousin once removed, via a different line through the other parent.
That is hilarious.
