Born in 2332 in New Orleans, Louisiana, Benjamin is the son of Joseph Sisko, the chef and owner of the restaurant "Sisko's Creole Kitchen," or "Sisko's" for short. His birth mother was a human woman named Sarah. However, Sarah was possessed by one of the Bajoran Prophets (the entities that exist inside the Bajoran wormhole), and manipulated into marrying Joseph in order to conceive Benjamin. Sarah and Joseph were happily married until Sarah disappeared two days after Ben's first birthday, when the life-form left her body. She died in an accident several years later. Joseph eventually met and married another woman, who went on to raise Benjamin as her own son. Benjamin remained unaware of these events until well into his adulthood and long after he had otherwise made contact with the Bajoran Prophets. Ben has a sister named Judith, and at least two brothers.
