Apparently Oprah has a sister, she didn't even know about until recently. The talk show host recently revealed she has a half-sister. I found more details from CBSNews.com:

On Monday's episode of "The Oprah Winfrey Show," a sometimes-emotional Winfrey introduced a woman she identified only as Patricia, explaining how the woman's years-long search for her family culminated in a meeting with Winfrey on Thanksgiving Day of last year.

The discovery is "the miracle of all miracles," Winfrey told her audience.

Winfrey said she was stunned to learn about the sibling, telling her audience that when Patricia was born in 1963, Winfrey was 8 years old and living with her father. She did not even know her mother was pregnant.
