I love all the other names too! My cw just had an Adeline but spelled it Adalyn, so you might get a lot of misspellings if that way is becoming popular. FWIW I like your spelling a LOT better!
I can't think Fiona and not think Shrek. I do like Adeline and considered it for DD1 but H, MIL and I all pronounced it differently and that killed it for me.'
Ahhh, MMM and its strong opinions on baby names. I like them all. Fiona is a beautiful, classic Gaelic name. The rest of your names are just as lovely.
I am an outlier here, though, and can't get bent out of shape over anyone's name unless it's super hipster (Kale, Lava) or obviously made up.
My friend just named her daughter Fiona and calls her Fi Fi. Honestly my first thought when I heard her name was the movie Shrek.
If this baby was a girl, DD wanted to name her Fiona. That's also the name of a character in one of her favorite Barbie DVDs. I think it sounds pretty, but it now carries conotations to cartoon characters when I hear it.
