Could it also mean that there's a possiblity he could have a big brother? I mean if doffy was the youngest of the two he could be also refered as "young master"?

This may be out of place because there's not enough info but if doffy will eventually loose the shickibukai tittle and his supossed brother became one it could be the new shickibukai we don't know of yet and keep things at bay in Dresrosa with a new king...being doffy under his orders and making the straw hats plans go with more difficulties.
