Bowser Jr. is Bowser's son, or so says Super Mario Sunshine. And apparently, Peach is the mother, who in turn, didn't even know...BB? Baby Bowser? That's Bowser when he was little. Bowser Jr. is most likely the youngest, in fact I could have sworn seeing that somewhere on an official site/booklet/whatever.
