Which Queen of England had 11 fingers?

None. Legend has it that Anne Boleyn did, but upon exhumation no abnormalities were discovered.

"After her death a number of myths sprang up about Anne. Many of these stories had their roots in anti-Anglican works written by Roman Catholics. Nicholas Sander, a Roman Catholic recusant born c. 1530, was committed to deposing Elizabeth I and re-establishing Roman Catholicism in England... he was the first to write that Anne had six fingers on her right hand. Since physical deformities were generally interpreted as a sign of evil, it is unlikely that Anne Boleyn would have gained Henry's romantic attention had she had any.
