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 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")
Eliminated initiates
These fifty-seven initiates were personally eliminated from the program by the Dax symbiont dating back over a period of 200 years. In 2370, after learning this, Arjin initially asked to be reassigned upon hearing his field docent was to be Jadzia Dax. (DS9: "Playing God")
Ezri's father
The father of Janel, Ezri, and Norvo and husband of Yanas. By 2375, the couple had separated and he had left the Tigan home. (DS9: "Prodigal Daughter")
Guardian
This guardian visited Deep Space 9 in 2371. (DS9: "Facets")
Jadzia Dax's family
Mother
This woman was to be the recipient of a message Jadzia recorded in 2372 prior to a battle. After assuring Miles O'Brien that he would live to a ripe old age, Jadzia 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")
Sister
This woman sent her sister several glasses in 2372. Jadzia found them to be "really ugly". (DS9: "Body Parts")
Unlike Jadzia, she was not joined. (DS9: "Invasive Procedures")
Joining attendees
Nine individuals were present when the Dax symbiont was transferred from Curzon Dax to Jadzia Dax. Six of them wore medical gowns, so they might have been doctors. The remaining three wore civilian clothes and could possibly have been members of Jadzia's or Curzon's family. (DS9: "Emissary")
Odan's male hosts
Host 1
This host was thought of as Crusher's lover's father. He knew Leka Trion and had kept the people of Peliar Zel II at peace for several generations. In reality, he was the prior host of the Odan symbiont. The younger hoped his efforts would be as successful as the elder's. (TNG: "The Host")
Host 2
This host was originally believed to be Odan, but was in reality only a host body to the symbiont. Upon nearing death in 2367, he ordered Beverly Crusher to save the symbiont and not the body housing it. (TNG: "The Host")
Peers' hosts
These seven hosts all carried the Peers symbiont prior to its joining with Selin Peers. At least one, the first, was a woman. As of 2369, Selin Peers still recalled the symbiont's memories from that time. (DS9: "Dax")
Symbiosis Commission doctor
This doctor was working for the Symbiosis Commission and was murdered by Joran Dax. (DS9: "Equilibrium")
Symbiosis Commission guards
This male and female guard were working for the Symbiosis Commission and helped arrest Joran Dax for murder. (DS9: "Equilibrium")
