I [name_u]LOVE[/name_u] the nn [name_f]Millie[/name_f] but am not a fan of [name_f]Mildred[/name_f] or [name_f]Millicent[/name_f]…looking for something that could be a rock star for us to go with big bro [name_m]Maverick[/name_m].
(Not currently expecting just planning ahead) 
[name_f]Amelia[/name_f], [name_f]Emilia[/name_f], and [name_f]Emmeline[/name_f]
I also love the nn [name_f]Millie[/name_f]. I think [name_f]Amelia[/name_f], [name_f]Amelie[/name_f], [name_f]Emmeline[/name_f], and [name_f]Matilda[/name_f] all work as full names for it.
[name_f]Mila[/name_f]? [name_f]Romilly[/name_f]? [name_u]Milan[/name_u]?
[name_f]Camille[/name_f] or [name_f]Camilla[/name_f]
Thanks ladies! Never even thought of [name_f]Amelia[/name_f]! That’s a contender!
I have to say [name_f]Camille[/name_f], but I’m not sure it goes with [name_m]Maverick[/name_m].
[name_f]Camille[/name_f], [name_f]Matilda[/name_f], [name_f]Milana[/name_f], [name_f]Emily[/name_f], [name_f]Romilly[/name_f], [name_f]Melanie[/name_f], [name_f]Amelia[/name_f], [name_f]Amelie[/name_f], [name_f]Mila[/name_f], [name_f]Maelle[/name_f].
[name_f]Emilia[/name_f] and [name_f]Amelie[/name_f] are my favorite ways to get to [name_f]Millie[/name_f], although I like [name_f]Camilla[/name_f] and [name_f]Romilly[/name_f], too. There’s also [name_f]Milena[/name_f]/[name_f]Milana[/name_f], [name_f]Aemilia[/name_f], [name_f]Amelia[/name_f], [name_f]Emmeline[/name_f], [name_f]Emiliana[/name_f], etc.
I just listed [name_f]Millie[/name_f] as one of the two worst names I’ve ever heard…but maybe she’ll convince you to call her [name_f]Mila[/name_f]…Milagra, [name_f]Melisande[/name_f], [name_f]Melanie[/name_f], [name_f]Melody[/name_f], [name_f]Marielle[/name_f], [name_f]Marie[/name_f]-[name_f]Louise[/name_f], so many options.
More unusual suggestions: [name_f]Milana[/name_f], [name_f]Milena[/name_f], [name_f]Emiliana[/name_f], Maximiliana, Maximiliane, [name_f]Romilda[/name_f], [name_f]Melinda[/name_f], [name_f]Melita[/name_f].
