I love [name]Amelia[/name] and nn [name]Millie[/name]! It’s so adorable for a baby girl…but also respectable as an adult.
In terms of a middle name…both go well…but I prefer [name]Renee[/name]. [name]Amelia[/name] [name]Renee[/name] Gross is easy to articulate.
Good luck!
Under normal circumtances, I’ll choose [name]Annabelle[/name] because, well, it’s on my list. I’m biased. But with your middle names choice, I think I’d pick [name]Amelia[/name]. [name]Amelia[/name] [name]Kathleen[/name].
I slightly prefer [name]Annabelle[/name] to [name]Amelia[/name], as I think [name]Amelia[/name] is getting a bit more popular/trendier - although it’s still a lovely choice.
[name]Renee[/name] and [name]Louise[/name] seem like “filler” middles, although if they’re family names, that shouldn’t matter. But [name]Kathleen[/name] has a fresh feel as a middle name, and I just generally like it better.
I don’t think any of your choices are bad, though.
[name]Amelia[/name] flows better with the last name for some reason (and I just like it better! Especially with the nickname [name]Millie[/name]) [name]Amelia[/name] [name]Renee[/name] and [name]Amelia[/name] [name]Kathleen[/name] are great choices.
