Goku's father was Bardock, and his mother was Gine. He also had a brother named Raditz.
obviously Patrick burlace and tony louros. In the DragonballGT movie, it is unknown who Goku jr's parents were nor what happened to them. It is only known that he is Pan's only grandson, which makes Goku his great-great-grandpa. I think goku jr is the son of goten and vegeta jr is the son of bra of trunks

Goku was surprised that Vegeta was the father of Trunks (and so the wife of Bulma), but he was happy for Vegeta and Bulma and didn't think it was "bad."
goku comes back to life many times
Trunks reveals the identity of his parents, Vegeta and Bulma, to Goku during the "Android Saga" in "Dragon Ball Z." This occurs when Trunks travels back in time to warn Goku about the impending threat of the Androids. The revelation serves to establish Trunks' motivations and connection to the timeline, as he hopes to change the future for the better.
