Maybe. Probably I wouldn't bother, I'd just pick two names I liked, but if I had a twin "set" in mind that I liked, I don't think I'd avoid it. I don't think I'd mind, if I were named a matching name with a twin, as long as it wasn't blatant and corny (like,
Dawn and Evening,
Faith and
Hope), and as long as it didn't feel like one name was clearly chosen only to "match" the other rather than for its own sake (like,
Brandy and Benedictine, or
Tabitha and
Dorcas). I think some rhyming names are okay, alliteration is fine, and meaning-matches are usually okay if the names themselves are both nice.
