Oh,
Ingrid is definitely a sweet moniker for a wee lass. It works well on a little one and grows with the child. If you don't think so, just look up a picture of
Princess Ingrid Alexandra of Norway. Definitely a little darling and her name just fits her. :)
I think
Greta can stand on its own, thanks to Miss Garbo. It's lovely.
Of the two names, I think
Ingrid works best with
Evadne. Both have this mythological aura about them. While
Greta is utterly gorgeous, I think it's in a different category altogether than
Evadne and each would sound out of place next to the toher.
