Most names I like are somewhat nature-y so I’m sub-categorizing.
Gems: [name_f]Opal[/name_f], [name_f]Emerald[/name_f], [name_f]Peridot[/name_f], [name_f]Topaz[/name_f], [name_f]Amber[/name_f]. I would use [name_f]Opal[/name_f] and maybe [name_f]Emerald[/name_f] up front, the others probably only as middle names.
Animals, words: [name_u]Dove[/name_u], [name_f]Calico[/name_f], Kestrel, [name_f]Wren[/name_f]. These are all middles for me.
Trees, words: [name_f]Magnolia[/name_f], [name_f]Maple[/name_f], [name_f]Hazel[/name_f], [name_f]Acacia[/name_f], [name_f]Lilac[/name_f].
Flowers and plants, words: [name_f]Rosemary[/name_f], [name_f]Saffron[/name_f], [name_f]Lily[/name_f], Betony, [name_f]Azalea[/name_f], [name_f]Briar[/name_f], [name_f]Felicia[/name_f]*, [name_f]Veronica[/name_f], [name_f]Marigold[/name_f], [name_f]Viola[/name_f], [name_f]Fern[/name_f], [name_f]Ivy[/name_f], [name_f]Jessamine[/name_f], [name_f]Bryony[/name_f], [name_f]Clover[/name_f].
Name(s) with gemstone meanings: [name_f]Esmeralda[/name_f]/[name_f]Esmerelda[/name_f] is my favourite.
Names with animal meanings: [name_u]Yael[/name_u], [name_f]Tabitha[/name_f], [name_f]Raquela[/name_f], [name_f]Giselle[/name_f], [name_f]Ursula[/name_f], [name_f]Lupe[/name_f], [name_f]Dvora[/name_f], [name_f]Yonina[/name_f], [name_f]Mariposa[/name_f], [name_f]Ayelet[/name_f].

Weather, seasons, and meanings related to same: [name_u]Rain[/name_u], [name_u]Winter[/name_u], [name_f]Autumn[/name_f], [name_f]Aviva[/name_f], [name_f]Gwyneira[/name_f].
I can provide the meanings/language background for all the foreign-language ones I just didn’t want to put up a huge post.
*I think this might be backwards and the flower be called [name_f]Felicia[/name_f] after someone’s name and not vice versa. Same for [name_f]Veronica[/name_f].
