Silva La Forge was a command division officer in Starfleet, and the mother of one son, Geordi, and one daughter, Ariana. Her husband, exozoologist Edward M. La Forge, served as a sciences division officer in Starfleet.
Young Geordi spent time with both his parents as a child, sometimes separately. For a time, Geordi lived with Edward while he studied invertebrates in the Modean system. On other occasions, Geordi would instead be away from Edward, on outposts near the Romulan Neutral Zone with mother Silva. (TNG: "Imaginary Friend")
By 2369, she held the rank of captain and was the commanding officer of the USS Hera. The vessel went missing in 2370, and Silva and the rest of the vessel's crew were listed as missing in action. Subsequent search missions by starships USS Noble and USS Excelsior reveal no trace of the ship's whereabouts or fate. She was survived by her husband and children. (TNG: "Interface")
