Actually, Luffy was raised by Garp only up until Luffy was 7 or 8, after which he was left in the care of Dadan, who by that time, was already taking care of Ace since he was a baby. Dadan isn't elaborated on or shown, no one knows if Oda will make a backstory on Dadan (hope he will).

And it's Gol D. Roger, not Gold. D. Roger..It was pointed out by Dr. Kureha during the end of Chopper's Arc that his name is actually Gol D. Roger and not Gold Roger (she comments, " ..is that how they call him these days?").
