Triplet Name HELP!!!!

Hello,
Recently I found out I was having two boys and a little girl! We have almost chosen the boys name with ones of the middles names to be decided. However in the case of the girl we cannot agree on a name. The name we came up with, does not seem to match her brothers but i really like her first name. Any opinions or suggestion would be greatly appreciated
Boy 1- [name_m]Orson[/name_m] [name_m]Willis[/name_m]
Boy 2 - [name_u]Ashby[/name_u] [name_m]Finton[/name_m]/Finto?
Possible name for Girl- [name_f]Emilia[/name_f] [name_f]Juliana[/name_f]?
