I would probably go with another 5-letter name, and probably ending in an A, since [name_f]Elise[/name_f] and [name_f]Maeve[/name_f] share the same ending vowel… [name_f]Julia[/name_f] is my first thought, probably because of another family I knew from another name site - they had twin girls, [name_f]Julia[/name_f] and [name_f]Clara[/name_f], and then two additional girls, [name_f]Eliza[/name_f] and [name_f]Anika[/name_f]. [name_f]Elise[/name_f], [name_f]Clara[/name_f], and [name_f]Julia[/name_f] just feel like they fit together perfectly because of it!
I also love:
