Sisko family

From Memory Alpha, the free Star Trek reference.

The Sisko family is the extended family group around Benjamin Sisko. With his first wife, Jennifer, he fathered their only son, Jake. Ben and Jennifer met on Gilgo Beach in 2354, and she died at Wolf 359 in 2366. (DS9: "Emissary")

Ben's parents were Joseph and Sarah. Joseph and Sarah had met in Jackson Square, New Orleans in 2331. After Sarah left Joseph in 2333, a year after Ben was born, Joseph spent three years looking for her before eventually remarrying and having two more sons and a daughter, Judith. (DS9: "Image in the Sand", "Past Tense, Part I", "Paradise")

Jake introduced Ben to Kasidy Yates in 2371, and Ben and Kasidy married in 2375. Shortly before Ben ascended to join the Prophets, Kasidy became pregnant. (DS9: "The Dogs of War")

In an alternate timeline, Jake married Korena, a Bajoran woman. They later split up after about eight years. (DS9: "The Visitor")
