* Likely Irish: Anne Bonny was born in County Cork, Ireland, and most likely spoke with an Irish accent.
* Possible influences: As a pirate, she traveled widely and would have encountered many different accents. She likely picked up some linguistic traits from her travels, particularly in the Caribbean.
It's important to remember that accents are constantly changing. Even if we could travel back in time and hear Anne Bonny speak, her accent would probably sound very different to our modern ears.
However, when portraying Anne Bonny in fictional works, many writers and actors choose to give her an Irish accent, reflecting her origins.
