I really love the name [name_u]Max[/name_u] for a girl. Are there any longer names that’s [name_u]Max[/name_u] could be a nickname for or middle names that would make [name_u]Max[/name_u] sound more feminine. I know [name_f]Maxine[/name_f] I just really don’t like it and [name_m]Maxwell[/name_m] seems to masculine. I would like my daughter to have the choice of the cool NN or a pretty name.
My favorite is [name_f]Maxima[/name_f]
Seconding [name_f]Maxima[/name_f]! She’s ridiculously lovely.
There is Maximilienne, too, but I like [name_f]Maxima[/name_f] much more, personally. 
Yes, [name_f]Maxima[/name_f] is wonderful! She has such a beautiful spunk.
You could also go a different route and choose a name like [name_f]McKenna[/name_f] or [name_u]Mackenzie[/name_u], and use [name_u]Max[/name_u] as a nickname.
[name_f]Laxmi[/name_f]
[name_f]Maxima[/name_f]
[name_f]Xiomara[/name_f]
