The following is a list of unnamed El-Aurians.
Guinan's father was an El-Aurian male born sometime before the 17th century. He was described as alive and well in the year 2369. (TNG: "Rascals")
In 1893, after running into a time-lost Data, Guinan questioned whether her father had sent him to retrieve her. Data insisted that her father had not sent him. (TNG: "Time's Arrow")
Guinan's mother was an El-Aurian female born sometime before the 18th century and the sister of Terkim. She was still alive in 2366.
Guinan reminded her of her brother Terkim, both of which had a sense of humor and didn't fit in. (TNG: "Hollow Pursuits")
These El-Aurians were transported from the SS Lakul and the SS Robert Fox aboard the USS Enterprise-B in 2293 after the two starships were caught in the nexus. Scotty was able to rescue 47 of them and beamed them directly into the ship's sickbay where two journalists and Pavel Chekov cared for them and treated their wounds. The El-Aurian survivors all seemed very shocked about this event. Among them were Guinan and Tolian Soran. (Star Trek Generations)
The El-Aurian survivors were played by SAG actors and most of them received no credit for their work as day players. According to Kristopher Logan a handful were picked and received credit for their work although they had no dialogue. Among the credited actors are Kristopher Logan, Marcy Goldman, Judy Levitt, Jim Krestalude, and Gwen Van Dam but some of them had no screen time in the final cut of the film.
