For girls I see [name_u]January[/name_u], [name_f]April[/name_f], [name_f]May[/name_f] and [name_u]June[/name_u] as being very usable
For boys: [name_u]August[/name_u]
Lately Nameberry has been making ones like [name_u]December[/name_u] and [name_u]October[/name_u] seem more commonplace in the forums.
I think the only one I’m really not feeling is [name_u]March[/name_u]. Not only is it a month but it’s a verb as well. I feel the child would hear the puns coming left and right.
The names [name_u]August[/name_u], [name_f]May[/name_f], [name_u]June[/name_u] and [name_f]April[/name_f] are so classic and familiar I don’t necessarily think some jump straight to it being a month name and therefore think there’s some correlation in regards to when they were born. So I feel they could easily be used in any month. A [name_u]December[/name_u] in [name_u]July[/name_u] might get a few raised eyesbrows.
