[name_m]Hi[/name_m] there.
Your kids’ names are very nice. You did a fantastic job w/your other little girl. [name_u]Eloise[/name_u] is adorable.
Here are my thoughts on your list:
[name_f]Willa[/name_f]-I don’t love this, but I like it. It goes well w/your crew. It’s kind of old fashioned & a little quirky, but smart & down to earth. I don’t like the nn ‘[name_u]Willie[/name_u]’ at all, which could be somewhat difficult to avoid.
[name_f]Lacey[/name_f]-This is not my personal favorite, but I can see the appeal. It has sort of a sweet flow-y sound. I understand why you’d want everyone to have different initials, but if this is the only one you really love I’d go for it anyway. More important to love the name than have it fit w/your other kids’.
[name_u]Blaire[/name_u]-This is okay. It doesn’t sparkle for me, but it’s not bad. I think the ‘e’ looks off though. [name_u]Blair[/name_u] seems more polished.
[name_f]Felicity[/name_f]-This is beautiful. Sort of sassy & girly, but also kind & homey.
[name_f]Delilah[/name_f]-I’m not a fan of this one. It’s kind of popular in my area, so I’m a bit sick of it & it seems sort of snooty.
[name_f]Luella[/name_f]-So cute! I’ve recently fallen for this name. It’s just charming & fun to say.
[name_f]Mallory[/name_f]-I used this name for one of my favorite dolls when I was a kid, so I kind of like it for that reason! It’s different w/out being too out there.
[name_u]Sheridan[/name_u]-I’m not a huge fan of this. It reminds me of the hotels w/the same name.
Here are some names that maybe fit your style:
[name_f]Adelie[/name_f]
[name_f]Adele[/name_f]
[name_f]Bridget[/name_f]
[name_f]Claire[/name_f]
[name_f]Daisy[/name_f]
[name_f]Daphne[/name_f]
[name_f]Gemma[/name_f]
[name_u]Haley[/name_u]
[name_f]Natalie[/name_f]
[name_f]Phoebe[/name_f]
[name_f]Romilly[/name_f]
[name_f]Sadie[/name_f]
[name_f]Scarlet[/name_f]
[name_f]Tallula[/name_f]
[name_f]Tessa[/name_f]
And here are my favorite girl names: (this is hard, because I also find boy names way easier.)
[name_f]Guinevere[/name_f]
[name_f]Gerty[/name_f]-only as a nn, but I don’t love any full names for it. : /
[name_f]Eleanor[/name_f] nn [name_f]Nellie[/name_f]
[name_f]Amelia[/name_f] nn [name_f]Mia[/name_f] (my cat!)
[name_f]Fiona[/name_f] (my dog!)
And still like a lot, but maybe not as in love with:
Clemenetine
[name_f]Lilia[/name_f]/[name_f]Lili[/name_f]
[name_f]Miriam[/name_f]
[name_f]Livy[/name_f]-I like [name_f]Olivia[/name_f] & [name_f]Olive[/name_f] but not enough, & [name_f]Livy[/name_f] is too nick-namey…
[name_f]Ruth[/name_f] nn [name_f]Ruthie[/name_f]
[name_f]Stella[/name_f]…or maybe [name_f]Estella[/name_f]
[name_f]Hope[/name_f] this helps.
