[name_m]Hi[/name_m] there.
Here are my thoughts:
[name_m]George[/name_m] (family name)-This is nice. I think it goes well w/your kids names. It’s a strong classic, but isn’t super over done. It’s friendly yet masculine.
[name_m]Oscar[/name_m] (family name)-Ooh, I love this. Vintage, yet a little quirky. It fits in great w/your crew.
[name_m]Warner[/name_m] (family name)-Hm. I think that this would be nice as a mn.
[name_m]Thaddeus[/name_m] (I like that it is an apostle’s name)-This is cool. It’s not what I’d pick w/[name_u]August[/name_u], [name_f]Corinne[/name_f] & [name_m]Simon[/name_m], but it doesn’t not fit either. I love all of the nn options: [name_u]Teddy[/name_u], [name_m]Thad[/name_m], [name_m]Tad[/name_m], Thax, [name_m]Thatch[/name_m].
[name_m]Theodore[/name_m] (like the meaning and the nickname options)-Me too! Other than [name_u]Theo[/name_u], you can do all of the same nns w/[name_m]Thaddeus[/name_m]. And [name_m]Thaddeus[/name_m] is more unique. [name_m]Theodore[/name_m] is adorable though.
[name_m]Phillip[/name_m] (apostle’s name again) -This is a nice solid classic. I find [name_u]Phil[/name_u] dated, but love [name_m]Pip[/name_m] & [name_u]Flip[/name_u] if you’re into those.
[name_m]Anders[/name_m] (Scandinavian version of [name_m]Andrew[/name_m] and we have a Swedish last name) -That’s fun. It’s different.
[name_u]Everett[/name_u] (just like it)-This is nice, but I feel like since it has less meaning than the rest I’d eliminate it.
I’m really no help, because I like all of your names. If you’re looking for something less common, I’d go w/[name_m]Thaddeus[/name_m] or [name_m]Anders[/name_m]. [name_f]Do[/name_f] you like [name_u]Andy[/name_u]? That may be hard to avoid w/[name_m]Anders[/name_m].
[name_f]Hope[/name_f] this helps.
