Columba

This name is lovely! However, it does make me think of the pigeon horntail wasp, Tremex Columba.
Personally, that makes me want to use it more, because nobody would ever realize I named my child after a wasp; though I realize that's probably not most people's cup of tea.

For some odd reason, I actually really like this name. It makes me think of Columbus, Columbia, Columns, the flower Columbine, and going on an adventure.
