Looking for a name for a baby that honours two family members.
The obvious being [name_f]Pauleen[/name_f]. I’d rather something with a nice meaning, but have come to a bit of a roadblock.
Open to different styles and a mixture of gender specific and unisex. [name_f]My[/name_f] son has a unisex name.
[name_f]Maureen[/name_f] is a variation of [name_f]Mary[/name_f]. There might be some inspiration in this list for you! 
How about [name_f]Polly[/name_f] for a girl? It shares a sound with [name_m]Paul[/name_m] (or kind of does, depending on your accent) and it is another ‘Mary’ name like [name_f]Maureen[/name_f].
[name_f]Maura[/name_f]?
[name_f]Paulina[/name_f], [name_f]Pauline[/name_f], [name_f]Polina[/name_f] and [name_m]Paulino[/name_m] are the most intuitive options.
I may also consider the following names with similar sounds or letters:
[name_f]Paislee[/name_f]
[name_m]Pearlie[/name_m]
[name_f]Pansy[/name_f] - “thought”
[name_f]Peony[/name_f]
[name_f]Poppy[/name_f]
[name_f]Presley[/name_f]
Polianna
[name_f]Praise[/name_f]
[name_f]Maple[/name_f]
[name_m]Murphy[/name_m]
[name_f]Aurelia[/name_f]
[name_m]Aurelio[/name_m]
[name_f]Aubree[/name_f]
[name_f]Audrey[/name_f]
[name_m]Augustine[/name_m]
[name_f]Laureen[/name_f]
[name_m]Laurie[/name_m]
[name_f]Opaline[/name_f]
[name_m]Paul[/name_m] means “small” or “humble”. Names with similar meanings:
[name_f]Cosette[/name_f] - “little thing”
[name_f]Lillemor[/name_f] - “little mother”
[name_m]Orson[/name_m] - “little bear”
[name_f]Zita[/name_f] - “little girl”

[name_f]Nina[/name_f] - “little girl”
[name_m]Vaughn[/name_m]- “little”
[name_f]Rochelle[/name_f] - “little rock”
[name_m]Oisin[/name_m] - “little dear”
[name_f]Pipaluk[/name_f] - “sweet little thing who belongs to me”

[name_f]Talitha[/name_f] - “little girl”
[name_m]Ryan[/name_m] - “little king”
[name_f]Ursula[/name_f] - “little bear”
Adding:
[name_m]Aurelian[/name_m]
[name_m]Shaun[/name_m]
[name_m]Raul[/name_m]
[name_m]Amaury[/name_m]
Nicolaus
[name_m]Augustin[/name_m]
[name_m]Maurus[/name_m]
[name_m]Auden[/name_m]
[name_m]Laurentin[/name_m]
[name_f]Claudine[/name_f]
[name_m]Austin[/name_m] / [name_m]Austen[/name_m]
I’m just going to second @Estrela and say [name_f]Paulina[/name_f]! Such a cute name and feels fresher than [name_f]Pauline[/name_f].
I looked up the meaning, I could sort of see why “small and humble” wouldn’t be the most ideal meaning for a girl’s name, but it’s not bad either. I think in your case, the meaning is in the honor, so I wouldn’t let it stop you!
For [name_m]Paul[/name_m]
[name_f]Apolline[/name_f]
[name_f]Opal[/name_f]
[name_f]Pauline[/name_f] / [name_f]Polina[/name_f]
[name_f]Polly[/name_f]
For [name_f]Maureen[/name_f]
[name_f]Cora[/name_f] / [name_f]Flora[/name_f] / [name_f]Nora[/name_f]
[name_f]Mara[/name_f]
[name_m]Ori[/name_m] / [name_f]Oriana[/name_f]
[name_f]Rena[/name_f] / [name_f]Reena[/name_f] / [name_f]Rina[/name_f]
I sort of think [name_f]Polly[/name_f] would work for both (Mary historically has roots in [name_f]Polly[/name_f] and [name_f]Maureen[/name_f], while [name_m]Paul[/name_m] to [name_f]Polly[/name_f] feels more obvious). But I like the idea of [name_f]Opal[/name_f]! Maybe [name_f]Opal[/name_f] [name_f]Mary[/name_f] or [name_f]Opaline[/name_f] for both.
[name_m]Paul[/name_m] + Maureen…
[name_f]Polly[/name_f] (can derive from [name_f]Paulina[/name_f] and Maureen/Mary)
[name_f]Molly[/name_f] (similar sounds to [name_m]Paul[/name_m] and variation of [name_f]Maureen[/name_f]
[name_f]Aura[/name_f] (borrowing the AU letters from both)
[name_f]Aurelia[/name_f] (borrowing AU from [name_m]Paul[/name_m], AUR from [name_f]Maureen[/name_f], the L from Paul)
[name_f]Apolline[/name_f] (Pol from [name_m]Paul[/name_m], ‘-ine’ from Maureen)
[name_m]Mauro[/name_m] (borrowing MAUR- from [name_f]Maureen[/name_f] and AU from both?)
[name_m]Auden[/name_m] (AU from both, -en from end of Maureen)
[name_f]Lauren[/name_f] (LAU from [name_m]Paul[/name_m], aure-n from Maureen)
[name_f]Palmer[/name_f] (Paul + Maureen)
Meryl
Penny
Peony
Maury
With [name_f]Maureen[/name_f] being a [name_f]Mary[/name_f] variation, maybe [name_f]Mary[/name_f] + [name_m]Paul[/name_m] = [name_m]Perry[/name_m]?
