A Different Genealogy Question

[Hayabusa]

I'm a Star Wars fan as well as an RPG (it's like Dungeons & Dragons, only in the Star Wars universe) player. Some players, myself included, like to play along a certain bloodline of original characters to keep some kind of personal continuity. Thing is, with over 170 years of time in which to play from the beginning of Episode I to a comic series that takes place 137 years after the original Star Wars movie, that's a lot of characters to keep track of, far more than what notebook paper can do.

The question is this: I need a free family tree maker that allows direct data input into the life of a person being included. Most importantly of all, I need a family tree maker that allows me to input a birth date of 32 BBY, which is impossible on the site I'm currently using now.
