Gohan is Kakarot's son, yes. It took a lot, but Vegeta ended up on Earth too after a while. I'm his son, not that he really seemed to want anything to do with me.
[Okay, maybe letting a hint of old bitterness into that. They may be on good terms now, and his timeline's version of Vegeta had the excuse of being dead. But the Vegeta of the other timeline HADN'T wanted anything to do with Trunks really, not until they were fighting Cell, and especially not until after Trunks had died.
Of course, now that it's been pointed out, taking out the hair and eye-color, Broly might be able to see the resemblance between Vegeta and Trunks. Except Trunks is friendlier and more open. Get him to scowl or smirk, and it'd be more obvious.]
As I said, it's a long story, and complicated. I don't have all the answers--I'm not sure anyone here does, but I can call someone who might have more than I do. Would that help?
