User blog comment:CNBA3/Luffy's Mother Theory!/@comment-3345720-20150328145035

I'm not sure about this one, but there's a theory that it's jewelry bonney.

Same height, same eating habits, some sort of connection with the WG, interesting age-altering ability, and the seemingly significant naming. (Continuing with the treasure series- Gold Roger, Silvers Rayleigh, Jewelry Bonney.. plus Bonney is the name of a famous irl pirate [Anne Bonny])

Also, she was shown to be crying after the WB war, but that might just be her crying for WB and not Luffy. Who knows.

I got that from a japanese speculation forum somewhere. Personally can't see her with Dragon, but I thought the coincidences are pretty interesting nevertheless.
