[name_u]Loving[/name_u] the idea of a little girl called JJ or MJ lately. Drop your favorite combos with these initials below!
For reference, I’d describe our style as classic vintage with a hint of edgy/cool. Our son is [name_u]Maxwell[/name_u] and he would have likely been [name_f]Phoebe[/name_f] if he was a girl.
And…go!
These are so sweet. I love! I think a sibset of [name_u]Maxwell[/name_u] and [name_f]Phoebe[/name_f], [name_u]Maxwell[/name_u] and MJ, [name_u]Maxwell[/name_u] and JJ, or [name_u]Maxwell[/name_u], [name_f]Phoebe[/name_f], and MJ are all amazing. You cannot go wrong here!

@snowmaiden thank you so much! I am loving a lot of your suggestions, especially [name_f]Mary[/name_f] [name_u]July[/name_u], [name_f]Millie[/name_f] [name_u]Juniper[/name_u], [name_f]Maisie[/name_f] [name_u]Jubilee[/name_u] (!!!) and [name_u]Merritt[/name_u] [name_u]January[/name_u]. [name_f]Margot[/name_f] [name_f]Josephine[/name_f] is a combo we both loved for [name_u]Max[/name_u], too! I’ve also been thinking of [name_u]Merritt[/name_u] lately and am really digging her.
@littlekingtrashmouth thank you! [name_f]Mara[/name_f] has been growing on me a lot lately. [name_f]Mara[/name_f] [name_f]Juliet[/name_f] is a great combo!
@samosier24 love [name_f]Maeve[/name_f] [name_f]Josephine[/name_f]! We have [name_f]Josephine[/name_f] on our list!
@greyblue love your suggestions, as always. [name_u]Juno[/name_u] is so, so great but she kind of clashes with our last name. Makes me sad! [name_f]Margo[/name_f] [name_f]Juliette[/name_f] is really pretty!
[name_u]Juniper[/name_u] [name_u]Jean[/name_u]
