[name_m]Hi[/name_m] there.
Here are my thoughts on your lists-
Girls-
[name_f]Maddison[/name_f]-This doesn’t do much for me. It’s just kind of trendy & over done the past 20 years. Your daughters all have interesting feminine names, so I just don’t think that this fits.
[name_u]Marion[/name_u]-Ooh, this is fun. It’s unique, smart & kind. I really prefer [name_u]Marian[/name_u], because I think that [name_u]Marion[/name_u] is more of a male spelling. [name_m]Even[/name_m] though this name is rather feminine in my opinion.
[name_f]Maribel[/name_f]-So pretty! It’s not over done, yet simple & grows up well.
[name_f]Monica[/name_f]-This is one that I don’t see on lists very often. It’s not my personal favorite, but it’s not bad. Kind of refreshing.
[name_f]Hannah[/name_f]-Very sweet & simple. Super popular, but a lovely classic name. Maybe a little bit too simple w/your girls’ more fancy names, but not a deal breaker.
[name_f]Arielle[/name_f]-This is really pretty & goes well w/your crew. I think either way you spell it [name_u]Ariel[/name_u] or [name_f]Arielle[/name_f] it may have spelling or pronunciation issues. [name_m]Just[/name_m] something to consider.
[name_u]Brooklyn[/name_u]-I don’t care much for this one . It’s just kind of trendy & not very interesting.
[name_f]Belle[/name_f]-Ooh, that’s nice. I personally kind of like it for a nn. Especially since your other girls have nns. [name_f]Annabelle[/name_f] or [name_f]Bellatrix[/name_f] would be cool. Or [name_f]Mirabelle[/name_f]? [name_f]Maribelle[/name_f] may work.
[name_f]Sophie[/name_f]-This is sweet. Very popular, but a lovely name that fits in pretty well.
[name_u]Avery[/name_u]-Meh, I don’t care for this one. I know that it’s used for girls (soooo popular for girls), but it just seems like a boy name to me.
Boys-
[name_m]Archie[/name_m]-Cute! Charming & a little quirky. I like it for you. I also like [name_m]Archer[/name_m] nn [name_m]Archie[/name_m].
[name_m]Joshua[/name_m]-This is fine. It’s an ex boyfriend’s name, so I’m biased in not liking it. But it’ s a good classic name that works w/your crew.
[name_m]Marshall[/name_m]-This is certainly different. I don’t personally care for it, because I just picture a marsh, you know? But I wouldn’t be disappointed to meet a little [name_m]Marshall[/name_m] since you don’t hear it much these days.
[name_u]Maddox[/name_u]-I want to like this one, because names w/the letter ‘x’ are generally really cool. I think that I just don’t like the ‘mad’ part.
[name_m]Fabian[/name_m]-That’s interesting. I don’t care much for it, but it’s different & kind of cool.
[name_u]Sam[/name_u]-I love [name_u]Sam[/name_u]. I love. [name_m]Samuel[/name_m] nn [name_u]Sam[/name_u], but I don’t mind just [name_u]Sam[/name_u] really. It fits in well w/your crew. It’s just sweet, handsome, classic & friendly. Not much not to like.
[name_u]Jonah[/name_u]-This is a beautiful boy name. Very masculine, but just beautiful. That’s totally my style of boy names. It’s a bit common if that bothers you, but a great name.
[name_u]Dexter[/name_u]-This is cute. And I love the cool nn of [name_m]Dex[/name_m]. It’s simple & not terribly common. Fits in well w/your crew as well.
[name_u]Jackson[/name_u]-I don’t hate this name. It’s kind of cool & cowboy-y. But it’s just so darn trendy & over done recently.
[name_m]Wyatt[/name_m]-This is a cool cowboy name too. A little less popular. I quite like it.
Not sure if my rambling helped at all. [name_f]My[/name_f] personal favorites in general & w/your kids’ names (which are quite fun, by the way!) are [name_f]Maribel[/name_f] & [name_u]Dexter[/name_u].
[name_f]Hope[/name_f] this helps.
