Myrtle Corbin

http://en.wikipedia.org/wiki/Image:Myrtle_Corbin.jpg

Born in 1868, Myrtle Corbin had two separate pelvises, side by side — each of her large outer legs was paired with a small inner one. She could move the small ones, but they were too weak for walking.

The condition didn’t slow her down — she married a doctor at 19 and eventually gave birth to four daughters and a son.
