Trills have a first name and a family name. A joined Trill replaces their family name with the symbiont's name. Thus Ezri Tigan became Ezri Dax when she was unwillingly joined.

It recently occurred to me that I don't know Jadzia's family name. There doesn't seem to be any information on Memory Alpha. I suppose it was never stated onscreen.

Are there any novels/ comics/ other that have given a name for her?
