Ancestry.com is a great place to start. Begin by gathering the easy things from the relatives you still have like names and birthdays. You can then begin to grow your family tree :)
Have fun!
If you consider war time, and enlistment my grandfather,and uncle both killed people. If you count being stupid, negligent, and hard headed both my parents are murderers.
I very much consider my grandfather and uncle heros, my parents though, they are human filth and can very much rot in hell I only hope I get to fork them in the ass at least once in the underworld.
I don't know if I'm related to any kings or anything but I know that my grandpa was a drug lord. He died three years ago and his family didn't tell us until last year which I am assuming is because they didn't want us to find out about the inheritance.
My best friend is related to 2 kings.
I really wanna know about my past relatives.
Have fun!
