I did this a while back, and quite enjoyed it. Basically, I will put up some families and say how many sons and how many daughters each one has. At the bottom, I'll provide a list of names, and you make a sib set for each family. You get a point for each sibling you put in the correct family.
Oh, and it's first names only.
