[name_f]Love[/name_f] [name_f]Maxine[/name_f] “Max” because it has a very clear match with [name_f]Penelope[/name_f] “PJ”
[name_f][/name_f][name_f]Penelope[/name_f] and [name_f]Maxine[/name_f] are both vintage and chic. [name_m]Max[/name_m] and PJ are both androgynous and cool.
[name_f][/name_f]The others, like [name_f]Monroe[/name_f] or [name_m]Murphy[/name_m], match PJ but stick out a bit with [name_f]Penelope[/name_f] (I saw that you exclusively call her PJ but I still like the idea of a full name that works with Penelope). [name_f]Matilda[/name_f] “Mattie” works though I think [name_f]Mattie[/name_f] sounds so similar to [name_f]Maddie[/name_f] that it doesn’t feel as boyish.
