List of unnamed Trill.

Arjin's family

The father of Arjin was not joined to a symbiont, but wanted his daughter (Arjin's sister) to be. He was a pilot instructor on Gedana post for forty years. After his daughter was successful in passing the rigorous trials for being joined to a symbiont, she decided not to be joined, which went against her father's wishes. She left home, married her spouse and the two never spoke again. Because of this he told his son, Arjin, it fell upon him to be joined. Arjin's father died in 2369. (DS9: "Playing God")

This family was only mentioned in dialogue.

Eliminated initiates

Jadzia's family


This woman was the spouse to Kela, and the mother of at least two children, Jadzia and her sister; she lived into the 2370s. Since her daughter was in Starfleet, she would worry about her daughter's safety. Jadzia, in turn, recorded "last messages" in case she did not come back from a mission.

In 2372, prior to a battle, Jadzia assured Miles O'Brien that he would live to a ripe old age, and told him she'd put his latest "last message" to his wife and daughter next to her message to her mother. (DS9: "To the Death")
