On her birth certificate, Oprah is actually Orpah Gail Winfrey.
The media mogul once explained how her name came to be: “I was born in rural Mississippi in 1954. I was born at home. There were not a lot of educated people around and my name had been chosen from the Bible. My Aunt Ida had chosen the name, but nobody really knew how to spell it, so it went down as ‘Orpah’ on my birth certificate, but people didn't know how to pronounce it, so they put the ‘p’ before the ‘r’ in every place else other than the birth certificate. On the birth certificate it is Orpah, but then it got translated to Oprah, so here we are.”
