Quote from the Futility Closet:
In 2005, archivist George Redmonds discovered something surprising among English birth records of the 14th century: a girl named Diot Coke.
She was born in the West Riding of Yorkshire in 1379. Researchers at Britain’s National Archives believe that her first name is a diminutive of Dionisia and her last name a variation of Cook.
