I'm in the mode of searching for names that suit characters based on traits etc. I've found sites like http://www.20000-names.com/ to be very helpful, however it's hard to find names BASED on traits I'm after due to the large number of names and thousands of meanings. Ideally I'd like to look for names in reverse by selecting the trait (eg. greed, guardian etc) and find the names off of them rather than having to search through names in alphabetical order. Does anybody know of any sites that do this? I can't seem to find anywhere, I've been looking for them all day.

So you're looking for a website that has the etymology of forenames, organized by meaning an connotation.
