Media mogul Oprah Winfrey was named “Orpah” at birth after the biblical character in the Book of Ruth, according to Wikipedia. But people mispronounced her name regularly, and eventually “Oprah” stuck.
The late rap star and actor Tupac Shakur was given the name Lesane Parish Crooks at birth, according to People.com. His mother Afeni Shakur (born Alice Faye Williams) changed his name to Tupac Amaru Shakur when he was a year old, after her marriage to Mutulu Shakur.
She renamed her son after the Peruvian revolutionary Túpac Amaru II.
