List of polydactyl people

The following is a list of famous people who are, were, or are believed to have been polydactyl:

Considered authentic

Endre Ady, was born with six fingers, with an extra pinky, which was tied off with a thread, withered away and only a dot-like scar remained of it, and this feature contributed to his belief of being a kind of shaman, a chosen (or accursed) one, reflected a few times in his poetry as well
Antonio Alfonseca, relief pitcher for the Florida Marlins, as of May 2005. See a picture here [1]
Anne Boleyn, 2nd wife of Henry VIII - said to have had eleven fingers, although she only had a double fingernail and a lump on her little finger [2]
Toyotomi Hideyoshi, 16th century Japanese ruler
Pacal the Great, King of Palenque - said to have had six toes on his feet
Hrithik Roshan, a Bollywood actor - has an additional thumb on his right hand
Sir Garry Sobers, cricketer - had an extra finger on each hand (removed during childhood)
Giuseppe Tartini, Italian composer and violinist - had six fingers on his left hand
"Hound Dog" Taylor, an American blues musician - had an extra finger on his left hand [3]
Sid Wilson, an American DJ - was born with six fingers on each hand (removed during childhood)

Hannibal Lecter, fictional psychopathic psychiatrist created by the author Thomas Harris
The legendary Padeira of Aljubarrota a man-like woman who helped Portuguese soldiers in the Battle of Aljubarrota (1385)
Count Rugen, the six-fingered man in the comic adventure novel The Princess Bride by William Goldman (1973), as well as the movie adaptation, directed by Rob Reiner in 1987. His polydactyly had a part in the plot of the story, because he had a special sword crafted to be balanced properly for a six-fingered man to wield.

Marilyn Monroe is believed by some people to have had six toes on one foot, but this is an urban legend (due to two misinterpreted photographs) and is untrue. See http://marilynmonroepages.com/6toes.html for photographic proof.
David Sedaris is sometimes claimed to have a sixth toe on one of his feet, but in fact does not. The rumour appears to have been started by the owner of an Internet fansite, solely to see if he could successfully spread a rumour.
Ontario premier Mike Harris was the subject of a similar rumour in 1997, after a newspaper obtained a photo of him as a youth in swimming trunks and barefoot, in which he appeared, through the same type of optical illusion as the Marilyn Monroe photographs, to have six toes on one foot. Several days later, he showed his foot to the press to prove that he only had the usual five toes after someone agreed to donate money to charity for showing his foot.
