in dawnguard you can talk about your family with serana, you can sort of choose what was your relationship with your family, if you miss them, hate them or simply don't care.

also in morrowind within the prophecy, there is a line that says "A prisoner born on a certain day to uncertain parents".

I think that every hero have or had a family, that what make them ordinary at the beginning, before turning into great heroes, maybe some sort of blood lineage that your hero doesn't know and was long lost, even too his family.
