My favorite is [name]Madeline[/name], but I go back and forth myself regarding the lyn vs. line pronunciation and this spelling vs. [name]Madeleine[/name].
I would have probably voted for [name]Madeline[/name] but I don’t like that spelling, I prefer [name]Madeleine[/name]. However I voted for [name]Evelyn[/name] if it is pronounced [name]Eve[/name]-lyn.
Considering those, my list in order of preference would be:
Juliet
Blythe
Madeline
Meredith
Caroline
Evelyn
While I really like the name Avery in and of itself, I would only recommend it if you don’t mind trendy and popular names. The name might be to the 2010s what Taylor was to the 90s. But if you’re a sucker for surname names and find them classic (like me in many cases), that might override the trendiness aspect for you.
[name]Cecily[/name], [name]Meredith[/name], [name]Caroline[/name], and [name]Bridget[/name] are my favorites.
[name]Juliet[/name] is beautiful, but getting trendy. Could be nice in the middle though.
Are you considering different names for the middle place? [name]One[/name] middle or two? Any important family names you might incorporate? Deciding on middles might help you narrow it down.
