I've only read a couple of the DS9 novels. Do any of the other works reveal how Trills manage names through marriage and joining? For example, if (say) Bob Anor is joined to the Glyn symbiont, he becomes known as Bob Glyn. If he marries Suzy Toll, an unjoined Trill, does she become Suzy Anor, presumably (from the example of Ezri Tigan's unjoined family having 'normal' surnames)? What if she later becomes joined to the Brant symbiote? She'll go by Suzy Brant, but will her full legal name by Suzy Anor Brant? What if Suzy was already joined when she marries Bob? What last name do their children get? If there's no official word, what would you speculate happens? It seems to me it'd be quite difficult to keep track of Trill family records, even realizing that only ~300 Trill are joined annually, if the official method is to take the symbiont's name as the surname and completely forget the previous surname.
