I have a 1 syllable last name and am planning on giving my baby a 1 syllable middle name ([name]Rose[/name], in honor of her grandmother)… we thought a good 3 syllable first name would balance things out. So I thought this would be a good forum to get started and get some ideas! What is your favorite 3 syllable name? : )
[name]Francesca[/name]!
Hard… I like [name]Eleanor[/name], [name]Amelia[/name], and [name]Cecilia[/name] all about equally.
I have a few:
[name]Madeline[/name]
[name]Emmeline[/name]
[name]Juliet[/name]
Euleta
[name]Isabel[/name]
[name]Artemis[/name]
Euthenia
[name]Daniella[/name] and [name]Camilla[/name], as well as [name]Athena[/name].
[name]Juliette[/name]
[name]Vivienne[/name]
[name]Eveline[/name]
[name]Adelaide[/name]
[name]Aveline[/name]
[name]Abigail[/name]
[name]Geneva[/name]
[name]Katherine[/name]
[name]Avery[/name]
[name]Coralie[/name]
[name]Eleanor[/name]
[name]Meribel[/name]
[name]Priscilla[/name]
Quinalyn
My favorite 3-syllable name is [name]Isabelle[/name]. 
Followed by [name]Arianne[/name].
I also like:
[name]Lillian[/name]
[name]Verity[/name]
[name]Gabrielle[/name]
[name]Lydia[/name]
[name]Eleanor[/name]
[name]Eleni[/name]
[name]Viola[/name] (also love [name]Violetta[/name], but it’s 4 syllables)
[name]Serena[/name]
[name]Sophia[/name]
[name]Olivia[/name] (again, 4 syllables, but I love it! [name]Olivia[/name] [name]Rose[/name] would be really sweet)
[name]Vivienne[/name]
[name]Aurora[/name] ([name]Aurora[/name] [name]Rose[/name] would be very pretty!)
[name]Giovanna[/name] (depends on how you say it… when the beginning is more smooshed, like the Italian way, it sounds more like joe-VAH-nah, so three syllables…)
[name]Johanna[/name]
[name]Caroline[/name]
Good luck!
