[name_f]Lovely[/name_f] names! Focusing on a first name only I would try to find something classic that works with:
[name_f]Eliza[/name_f]
[name_u]Jack[/name_u]
[name_f]Ivy[/name_f]
[name_u]George[/name_u]
Maybe:
[name_f]Alice[/name_f]
[name_f]Lucy[/name_f]
[name_f]Annabel[/name_f]
[name_f]Cora[/name_f]
[name_f]Elsie[/name_f], [name_f]Elise[/name_f], [name_f]Lisette[/name_f] or [name_f]Beth[/name_f] might make lovely second middle name options. You have an [name_f]Eliza[/name_f] and used [name_f]Isabella[/name_f] and both are forms of the same name. Alternatives to [name_f]Elizabeth[/name_f] might make a nice way to tie all the girls names together & allow them to share a name connection
