Someone on here suggested [name]Madeline[/name] to me for our daughter and I love it. However, our other kids names are [name]Maeve[/name], [name]Oliver[/name] and [name]Henry[/name], and I’m worried [name]Madeline[/name] is too long compared to the others and would be too matchy with [name]Maeve[/name]. If so, we will most likely use it as the middle name. If you think that [name]Madeline[/name] doesn’t fit in, please give us other first name suggestions using the middle name [name]Madeline[/name]! And if you like [name]Madeline[/name] with [name]Maeve[/name], [name]Oliver[/name] and [name]Henry[/name], please list some possible middle names! I hope this isn’t too confusing, thanks! 
I think [name]Madeline[/name], [name]Oliver[/name], and [name]Henry[/name] go well together, but not with [name]Maeve[/name].
Other Ideas:
[name]Oliver[/name], [name]Henry[/name], [name]Maeve[/name], and
[name]Lily[/name]
[name]Sofia[/name]
[name]Gina[/name]
[name]Avia[/name]
[name]Ariel[/name]
[name]Terra[/name]
I think [name]Madeline[/name] is fine. It is not too similar to [name]Maeve[/name] except for sharing the same initial. [name]Oliver[/name] and [name]Madeline[/name] are the same number of syllables, so I don’t think length is an issue either. Maybe you like [name]Adeline[/name] or [name]Caroline[/name], if the initial things really bothers you?
I would do [name]Madeline[/name] [name]Rose[/name], [name]Madeline[/name] [name]Viola[/name], or [name]Madeline[/name] [name]Elise[/name].
