I am 29 weeks pregnant and still have yet to find the perfect name for my girl. I really loved the name [name_u]Marlow[/name_u] but my husband shot that down quickly. Apparently was the name of his grandma’s alcoholic dog, ha! [name_f]Madeline[/name_f] or [name_f]Ava[/name_f] are my fall back names but I just don’t love them and think they are still too common. Her middle name will be [name_u]Jo[/name_u]. I am just burnt out on reading lists of baby girl names and am searching for some more unique opinions. Thanks for the ideas!
I find [name_u]Marlow[/name_u] adorable as well! I’m going to just list an eclectic mix, hope something sticks out to you!

Congrats! Hopefully we can help
If [name_u]Marlow[/name_u]'s a no-go, what about [name_u]Marley[/name_u]? About 1,500 girls got the name in 2015, so that’s not ridiculously common. [name_u]Marley[/name_u] [name_u]Jo[/name_u] rolls off the tongue a little easier than [name_u]Marlow[/name_u] [name_u]Jo[/name_u] (though I do love [name_u]Marlow[/name_u]).
[name_f]Harlow[/name_f] is also quite similar, but uncommon.
And lastly, as suggested above, [name_f]Margot[/name_f] — traditional, feminine but with a bit of gravitas. Also uncommon.
Other uncommon names that come to mind based on your list:
[name_f]Ada[/name_f] [name_u]Jo[/name_u]

Too bad about [name_u]Marlow[/name_u]! My immediate thought was [name_f]Harlow[/name_f]. [name_f]Madeline[/name_f] and [name_f]Ava[/name_f] are giving me some old Hollywood type vibes.

My hubby doesn’t like it either. I think it is great.
My other option that starts with M was [name_f]Monet[/name_f] after the artist. He likes it so far. I just had to remind him it rhymes with [name_u]Rene[/name_u] ect.

[name_f]Ava[/name_f] reminds me of [name_f]Ziva[/name_f], [name_f]Avia[/name_f] and [name_f]Aviva[/name_f] which are beautiful and less common than [name_f]Ava[/name_f]. Or maybe [name_u]Eden[/name_u]?
[name_m]How[/name_m] about Marjena [name_u]Jo[/name_u]?
