[name_m]Hi[/name_m] there.
Here are my thoughts on your lists-
Boys-
[name_m]Boone[/name_m]-This seems so perfect w/your crew. It’s not my personal cup of tea, but it’s not a bad name & it just fits really well.
[name_f]Hazel[/name_f]-This is way popular for a girl, so I wouldn’t do it.
Girls-
[name_f]Primrose[/name_f]-That’s pretty. It’s a little frillier than [name_f]Magnolia[/name_f], even though they’re both flower names. [name_f]Magnolia[/name_f] just seems more adventurous & Southern.
Rosebud-I like it for a mn, but the ‘bud’ part just seems weird on a girl fn to me.
[name_f]Birdie[/name_f]-I prefer this as a nn for [name_f]Bridget[/name_f] or [name_f]Bernadette[/name_f] usually, but for you I like it a lot on its own!
[name_m]Fischer[/name_m]-I think that’d be good for a boy for you.
[name_f]Dovie[/name_f]-I’d do [name_u]Dove[/name_u] nn [name_f]Dovie[/name_f] if you like [name_f]Dovie[/name_f]. It seems better as a nn. It’s not my style, & not as prairie sounding (that’s a cute theme, by the way!) as your other kids’ names.
Sorry for any repeats, but how about…
