Well, I liked
Violetta Lavender's suggestion of
Aisling.
Some off the top of my head:
Mairead (although, with
Rosemarie, this might be a problem)
Moira/Maura (similar problem as above)
FinolaCaroline
The thing is, I have a bad association with a
Carina, which is why I said it was probably only me who would think it was out of place. Ooh! What about
Kerensa? Just a thought...
And what about
Desmond Gunther/Gunter? I know it isn't Swedish, but it has the same winter-y vibe I get from Swedish names...
