Anne Bonny (Cormac, 1702 – 1743) is the main ispiration of the character Jewelry Bonney in One Piece. She was an Irish woman who became a famous pirate, operating in the Caribbean. Launching her own career as a pirate, along with Mary and Rackham, she raised a small crew and escaped the island in August 1720, intending to execute a series of swift robberies before retiring with enough gold to live off.
Anne was a capable fighter, adept at wielding swords and firearms. She also had advanced freerunning skills, allowing her to keep up with Edward as he navigated Long Bay’s jungles. As well as this, Anne possessed great nautical knowledge, which served her well in her role as quartermaster.
The dates of birth and death are uncertain and the few biographical you have about her are due to the tales of Captain Charles Johnson (perhaps he is a fictional character due to Daniel Defoe), contained in “A General History of the Pyrates”.

Oda has revealed that Sanji’s birth and early history is likely to be revealed or at least touched upon in 2016. Oda has been building up to this and within two of his colour spreads he has left us two massive hints as to somebody important in Sanji’s life.

Firstly, the cover page of chapter 784:

There is a blonde female zombie biting Sanji’s right shoulder.

Now the cover page of chapter 811:

The can that Sanji is holding has this same woman on the front of the branding. The legible words on there are ‘All women are g….’, something strongly related to Sanji’s lifestyle and ideology, this character clearly has a huge impact on Sanji’s life

As for deciphering who it is: they are a fully grown woman when they died/are a zombie in the first colour spread. She is also blonde, perhaps a blood relative such as an older sister, mother or aunt?

‘These two women don’t look much alike’ or ‘it’s just a coincidence’ you say? Is it?

This coverpage which prossibly foreshadowed Jack has Luffy and Sanji wearing Gold ornaments, both have the faces of women on them. The time of Jack and 2016 are synonymous, so there may be more to this cover page than meets the eye

Here’s a possible bonus:

A crown on a woman… Is it possible Sanji really is royalty? The scarf Luffy uses on the snowman comprises of Yellow, Pink, Turquoise and Blue… the colours of the womans hair on the can that Sanji holds on the coverpage of chapter 811!

I personally think this woman is Sanji’s mother and the tragic figure in his background
