That is one of my favorite episodes too, though not for the same reasons, I just like it. I really haven't looked too far into my lineage, but talking about it makes me realize how lucky I am that I can talk to my family about such things. I like to talk to my grandmother especially because she is the main link. She tells me lots about my grandfather, who died before I was born. There are definitely some interesting stories down the line and I don't mind hearing them over and over (Lord knows I've heard each one of them about 8 million times). But just because you can't trace your biological history back too far doesn't mean you are just a piece of unidentifiable DNA! I hope you can find out more though, because it does tell you a lot about why you're the type of person you are. Good luck!
