Love it. One of the first mysteries I wanted to solve when I began this great genealogy adventure was how my grandparents were "double cousins" as she always liked to tell me. When I finally found out that they weren't biologically (as far as I know yet) related, but that the aunt of my grandmother and the uncle of my grandfather married, I let out a shout. I had solved it, and now I was hooked. I also love a mystery.
