Your father is dead. He's currently "someone else." He's not even your father right now. He's someone else. He won't necessarily be your father in the future if he's not now.
Like Frankk pointed out, there's a possibility that you'll all stick together, but not in the ways you currently are now. For all anyone knows, you could be his father in another life.

A person is a concept and doesn't exist. There exists only experience.

Close Family and friends tend to rebirth into the same family and circle of friends again and again, just as those in the living world tend to like to stick to their close ones. Your father could potentially come back as a son, niece, nephew, children of close friends, a pet, etc. depending on his karma and merits. Or if you and he both have strong positive karma, and he's in a godly realm, then humans with strong positive karma tend to have a bigger circle of friendly deities who lend a helping hand in this life. For example, family and friends of mine, and myself on occasion have experienced divine intervention preventing serious accidents. People who do lots of good attract benefactors, and seem to enjoy lots of good 'luck' in this life, and people who do lots of bad tend to have 'bad luck'. It's no accident.
