Gimmie two seconds on her brothers. Taban, Reon and Pohl, according to DS9 Lexicon, and Tracy is an outstandingly researched resource. (I've always thought it was funny that Mora is Pol, and Kira's brother is Pohl. Like Jon and John, or Alec and Alex, I suppose...)

As far as I'm aware of, there is no canon whatsoever on what Naprem did for a living before meeting Dukat. It's interesting that Ziyal has artistic gifts, which, considering that Meru was originally an icon painter, I think one fanfic has used to postulate that Naprem and Meru were really one and the same, just with Meru given another identity for whatsoever reason, but that's too much of a Victorian Novel kind of stretch for me. Hence the doctor idea.

There isn't, as far as I know. I happen to like the fanwank that Meru and Naprem are the same person, if only because then Ziyal and Nerys are halfsibs. Plus, the artistic thing. But I realize that the idea is a little farfetched. (Not as crazy as Tasha Yar though...) But the idea of Naprem as a doctor is also interesting, if only because the only educated Bajoran we know of who lived through the Resistance is Mora. (I'm Mora's only fangirl.)

You know what else is good, that I forgot to prop for? The tie-ins to Second Skin.
