Imagine it? I already ran a Dark Heresy game of it!
I don't feel that marines could have actual ancestors. What I do feel they can do is maintain relationships with their old families, which iirc the Ultramarines do considerably. In this way, a marine may know that his great grandfather's brother was chosen as a marine (and may still be fighting alongside him!) and the two can then relate to each other, remembering family and old stories.
Just because my friends children call me "Uncle Monkey" and use me like a Jungle Jim... Sheesh.
