I went alum 5 years ago, and my grandlittle joined my 'family tree' the following semester. I was still living in the town where I went to college, so I went to visit and meet her. Well, my husband (at the time) had family who shared her last name, and I mentioned that to her. She didn't think they were related, but after we had moved out of the area, I got a phone call from her. She had done some research into her family, and it turned out that she and my (then) husband were distant cousins.
