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 jewerly bonney.

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

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.
