Monkey D garps son is Monkey D dragon. Monkey D dragon's son is Monkey D luffy.

Gol D Roger and Portgaz D Rogue's son==> Ace

When Gol D Roger died, he GAVE Ace to Garp, cause he thought of him as a friend even though garp chased roger all over the seas. As previously said, when Luffy was young, Garp gave him to Dadan. Ace and Luffy are adoptive brothers, NOT blood brothers.
