Personally, I think Avonlea is great. It’s beautiful, distinctive and literary. It’s definitely unusual, but it’s not made up and people who know their literature will recognize it immediately- a perfect balance! I, personally, would love to be named Avonlea, because it has cool literary/cultural context and it’s quite unique without being weird (38 girls were named Avonlea last year- so it’s not totally unused!). I much prefer Avonlea to Novalee. Novalee does not sound nearly as distinguished or elegant as Avonlea. You could always call her [name]Nova[/name] (the first four letters inverted) as a fun nickname. The only problem is see with Avonlea is pronunciation, but such is the case with most unusual awesome names. I get how you’re feeling, but I would definitely keep the name around, maybe decide upon one or two other names you and your family really love, but definitely keep Avonlea on the list, because like you said, your daughter’s father and siblings have attached to the name, so that’s kind of important too, right?
Okay, so maybe the key is the middle name. [name]Rose[/name] is beautiful, but doesn’t compare to the unusualness of Avonlea. You could incorporate Novalee, a name your currently loving, and go with Avonlea [name]Nova[/name]. Avonlea and [name]Nova[/name] are different enough, I think, in sound (though similar, of course, in letters), and creates a cool parallel within the name. Or do you want something a bit more gender neutral, like [name]Adeline[/name]'s middle name? Something like Avonlea [name]Sloan[/name], Avonlea [name]Reese[/name] or Avonlea [name]Gray[/name] could work. Or something more feminine, but still one syllable like Avonlea [name]Gwen[/name], Avonlea [name]Pearl[/name], Avonlea [name]June[/name], or Avonlea [name]Maeve[/name].
[name]Hope[/name] that helps!
