There are a number of variations given for Oakley's family name, Mosey. Many biographers and other references give the name as "Moses". Although the 1860 U.S. Census shows the family name as "Mauzy", this is considered an error introduced by the census taker. Oakley's name appears as "Ann Mosey" in the 1870 U.S. Census and "Mosey" is engraved on her father's headstone and appears in his military record; "Mosey" is the official spelling by the Annie Oakley Foundation, maintained by her living relatives. The spelling "Mosie" has also appeared.
