I love [name_f]Lillian[/name_f] [name_f]Claire[/name_f]! With your son’s name it sounds perfect, and of course it’s stunning on it’s own, too. All your choices are gorgeous, but that would be my pick. Second choice would be [name_f]Georgia[/name_f] [name_f]Claire[/name_f] because I’m a sucker for the nickname [name_u]Georgie[/name_u], but I do think that [name_f]Lillian[/name_f] sounds so great with your other child.
I really like [name_f]Georgia[/name_f] [name_u]Wren[/name_u], [name_f]Lillian[/name_f] [name_f]Claire[/name_f], [name_f]Clara[/name_f] [name_f]Elizabeth[/name_f] or [name_f]Clara[/name_f] [name_f]Lillian[/name_f]. If I had to choose though I would say [name_f]Lillian[/name_f] [name_f]Claire[/name_f].
I love [name_f]Clara[/name_f]. I think it flows better with [name_f]Elizabeth[/name_f] but [name_f]Lillian[/name_f] is more unexpected as a middle name.
I have to vote for [name_f]Clara[/name_f] [name_f]Elizabeth[/name_f], one of my personal top two name combos!!
I think [name_f]Clara[/name_f] and [name_m]Ethan[/name_m] sound really nice together vs. [name_m]Ethan[/name_m] and [name_f]Lillian[/name_f]. There’s something about the repeated -an -an sounds with [name_m]Ethan[/name_m] and [name_f]Lillian[/name_f] that could be a bit of a month full when you’re calling for the kids on a playground. Unless you plan on calling her [name_f]Lily[/name_f], in which case I think it works fine.
[name_f]Georgia[/name_f] is pretty too, but I prefer the other two options.
