User blog comment:Will od D./Who is luffys mother/@comment-1691106-20101015013221

Makino is far to young to be Luffy's mother. Twenty-two years ago she was depicted as still being a child, far to young to conceive a baby in the next three years. Unless Dragon's a huge pedophile, there's no chance of that.

If Luffy's mother is even still alive, or if Oda even decides to write her into the story, she's probably a member of the revolutionary army like her husband or something of that nature.

You could also bring up the interesting question of who is Luffy's grandmother, somethings are just never answered.
