Hi there.
Here are my thoughts on your list-
Girls-
Penelope ‘[name_u]Penny[/name_u]’-This is so darn cute. I think it’s nice w/Evelyn too.
Josephine ‘[name_u]Josie[/name_u]’-This is even better. Old fashioned & classy. I kind of like [name_u]Penny[/name_u] more, but [name_f]Josephine[/name_f] & [name_u]Evelyn[/name_u] are darling.
Annabel ‘[name_f]Annie[/name_f]’-This is adorable & a little less common.
Katherine ‘[name_f]Kat[/name_f]/Kate’[name_u]Kit[/name_u]’-I’m really no help, because apparently I like your whole list. This is a solid smart classic like [name_u]Evelyn[/name_u]. And I really only like the nn [name_u]Kit[/name_u], personally. Or [name_f]Kitty[/name_f].
Juniper ‘[name_f]Junie[/name_f]’-I know sisters called [name_u]Evelyn[/name_u] & [name_u]Juniper[/name_u]! I always thought that they were a little miss-matched, but [name_u]Juniper[/name_u] is really fun none the less.
Magnolia ‘[name_f]Maggie[/name_f]’-[name_f]Magnolia[/name_f] is just gorgeous & has great southern charm.
Louisa ‘[name_u]Lou[/name_u]’-I just love [name_f]Louisa[/name_f]. It’s so classy yet a little quirky. I prefer [name_f]Lula[/name_f], [name_f]Lola[/name_f] or [name_f]Lulu[/name_f], but see the appeal of [name_u]Lou[/name_u].
Lucille ‘[name_f]Lucy[/name_f]/Lu’-This is even better w/Evelyn…not sure why. [name_f]Evie[/name_f] & [name_f]Lucy[/name_f] are so cute though.
Felicity ‘[name_f]Lissy[/name_f]’-I love [name_f]Felicity[/name_f], but just on its own. Not big on [name_f]Lissy[/name_f]. It sounds snobby for some reason.
Hazel-A nice vintage name. Kind of over popular though.
Stella-I love this one too. It’s a great balance of spunk, dramatic flair & just classic pretty-ness.
Boys-
Theodore ‘[name_u]Theo[/name_u]’-This is charming & a little quirky. Getting kind of popular, but for a good reason. I like [name_u]Teddy[/name_u] even more.
Benjamin ‘[name_m]Ben[/name_m]’-[name_m]Theodore[/name_m] & [name_u]Benjamin[/name_u] are my nephews (brothers). [name_u]Benjamin[/name_u] is a beautiful solid classic. [name_m]Just[/name_m] a tad over done though.
Archer ‘[name_m]Archie[/name_m]’-This is really cute & a little bit different.
Silas-This is cool. Kind of cowboy-y, but strong, smart & old fashioned.
James ‘[name_u]Jamie[/name_u]’-I like [name_u]James[/name_u] a lot. It’s a classic solid handsome name. I’m not big on [name_u]Jamie[/name_u] though. I prefer [name_u]Jem[/name_u] or Jass as a nn.
Joseph ‘[name_u]Joey[/name_u]’-[name_m]Joseph[/name_m] is handsome. I don’t care for [name_u]Joey[/name_u] though. It sounds kind of goofy to me.
Hayes-This is okay . It’s a bit more unique than a lot of your list.
Isaac ‘[name_m]Ike[/name_m]’-I think that [name_m]Ike[/name_m] is really fun. I like the nn [name_m]Zac[/name_m] too. [name_m]Isaac[/name_m] is a good solid name. A bit popular, but not too bad.
Maxwell ‘[name_u]Max[/name_u]’-I love this. It’s smart & sweet, w/a little spunk.
Declan ‘[name_m]Dex[/name_m]’-I love it! It’s sporty, handsome & kind.
Newton-This is not my style. A little too quirky.
Watson-This is quirky too, but I don’t know. It’s cuter than [name_m]Newton[/name_m]. I kind of like it. It’s really different.
