Here are my thoughts-
Ira-I adore [name_u]Ira[/name_u]. It’s simple & smart & a little quirky & old fashioned & sort of artsy. All the good things! Not at all popular, but well known.
Emery-I’m not huge on this one. It’s used for girls some, & I can’t decide if it feels feminine or masculine. It just feels a bit trendy over all.
Thatcher-Super cute. It has a fun cowboy vibe, or just a charming little ballplayer. It’s fairly easy but not at all popular. And has the cool easy nn of [name_m]Thatch[/name_m].
Guy-This seems a bit too simple or something. Maybe as a nn, but just feels weird as a name.
Wren-It’s not awful, but I think also used a lot more for girls. I love the bird connection, but the sounds feels bland to me.
Remy-That’s adorable. [name_m]Handsome[/name_m] & kind of witty. Simple & not over done.
