[name_u]Bellamy[/name_u] springs to mind! Generally for a boy.
I think [name_u]Lark[/name_u] or [name_f]Moon[/name_f] are the new [name_u]Wren[/name_u].
Anything with the nickname [name_u]Kit[/name_u] is still a huge one, the stretchier the better.
Agree with [name_f]Margot[/name_f].
There was a [name_f]Tiggy[/name_f] (sometimes [name_f]Antigone[/name_f] with Tiggy/Tig for short) phase for a while but I see that less at the moment. [name_u]Ziggy[/name_u] too
[name_u]Alma[/name_u] and increasingly [name_u]Alba[/name_u] are the new Ada; [name_f]Frida[/name_f] is the new [name_f]Freya[/name_f].
[name_f]Greta[/name_f], which I used to see a lot in the same category, has not caught on in the same way now that it’s so associated with Thunberg.
[name_f]Vita[/name_f], sometimes as a nickname, sometimes not.
[name_f]Birdie[/name_f] still, [name_u]Billie[/name_u], [name_f]Betty[/name_f].
[name_u]August[/name_u] still big, increasingly for a girl too. Nickname of choice now [name_m]Auggie[/name_m] or [name_m]Ozzy[/name_m] rather than [name_u]Gus[/name_u].
Fresh boy names ending in -ian: [name_u]Florian[/name_u], [name_u]Dorian[/name_u], [name_m]Cassian[/name_m], [name_m]Finnian[/name_m] and also sometimes [name_u]Vivian[/name_u].
[name_f]Finja[/name_f] has been and gone.
Where did [name_u]Jasper[/name_u] for a girl come from?!
