Marla, Mia, or Murphy? (just a name nerd, not expecting)

Good evening berries!
[name_m]Just[/name_m] collecting names for fun, not expecting any.
So I’ve been in love with [name_f]Marla[/name_f], [name_f]Mia[/name_f], and [name_u]Murphy[/name_u] lately, but want to decide on one so I can move on. I like [name_f]Marla[/name_f] because of its uniqueness, it’s special-sounding, and how it can both fit on a child and an adult. I like [name_f]Mia[/name_f] because of its sweet-sounding, and how it reminds me of a little princess. I also like [name_u]Murphy[/name_u] because of its uniqueness (of course), its special-and-soft-sounding, and its meaning “hound of the sea”.
So, what do you guys think so far, and what do you think would be a good middle name for the one(s) you like?
Note: for these three, I would really appriciated it if you can give me some three syllable names that rhymes with the first name.
Thanks a lot

My son is [name_u]Murphy[/name_u] [name_m]Ronan[/name_m] and we know 2 other male Murphys so its all boy in our house

I love [name_f]Marla[/name_f] though

I agree with pp that [name_u]Murphy[/name_u] is a boy’s name. I think [name_f]Marla[/name_f] is too weird, and looks like [name_f]Maria[/name_f] but with an extra bit of line in the spot of the i.

I like [name_f]Mia[/name_f] best. [name_f]Mia[/name_f] [name_u]Murphy[/name_u] could work as a combo. I like alliteration, but not a fan of rhyming names.

I agree. I also like [name_f]Mia[/name_f] the best of the three names.

[name_f]Mia[/name_f], hands down! Sweet, confident, ages well.
[name_f]Marla[/name_f] seems old-fashioned, like [name_f]Carla[/name_f] and [name_f]Darla[/name_f].
[name_u]Murphy[/name_u] is NOT a girls name.
