What about a name tradition where a name "concept" is passed on? ... Ok, I really don't like Claude names at all, but this is an immediate example:gen. 1: Claudine gen. 2: Claudette gen. 3: Claudia
Well, for some reason which goes against almost everything I wrote up there I consider Claudine, Claudette, and Claudia all the same name, so that doesn't bother me at all. *shrug*
Part may also depend if you're going for the meaning or the sound or both... I don't think of Claudia, Claudette and Claudine as the same name in and of themselves, but dif. feminizations of the same name.
