I actually think it's quite nice. I don't usually go for wordish names, but you are right about the calming, lovely image it conjures. The name itself makes me think of a writer or an anthropology professor--I'm not sure why! Evey is very sweet as a nn and I love the combos of Evening
Teresa and Evening
Rebecca . Other options perhaps:
Evening
RuthEvening
LydiaEvening
Coral Evening
Gloria (I like the play on morning glory here)
Evening
DelilahEvening
Melody (if we're going wordy, might as well go all the way!)
Evening
Anya
