I don’t like Vivian because the spelling causes confusion. Vivian is that guy from the Young ones. Vivien is okay but some people will spell it Vivienne. Will that bother you?
Lilian is nice. If people spell / pronounce it Lily-Ann, will that annoy you? People are annoying and someone will do that.
I like Valeria. I actually love Valerian when it appears in my garden.
