Favourite girl- [name_f]Odessa[/name_f] [name_u]Larkspur[/name_u]
I feel this is is such and unexpected, but so well matched combo. I always think of [name_f]Odessa[/name_f] gives very badass-warrior-princess vibes, but pairing it with such a beautifully whimsical nature name as [name_u]Larkspur[/name_u] transforms this combo into some kind of badass-fairy-princess-woodland-warrior-nymph. They flow so well together and just good good too!
This one was tough choosing, as I love several of your boys names 
Favourite boy- [name_u]Rhys[/name_u] [name_u]Meridian[/name_u]
[name_u]Rhys[/name_u] has been a name I have always loved, and one of those name I love a little bit more every time I hear it. I have a thing for Welsh names (and [name_m]Wales[/name_m] in general tbh) and [name_u]Rhys[/name_u] is probably my favourite. [name_u]Meridian[/name_u] is a very special name to me, and SUCH an underrated name that does not get used nearly enough! I hate to repeat myself, but I think this is another unexpected but beautifully matched combo. I love the strongness of [name_u]Rhys[/name_u] follwed by the softness of [name_u]Meridian[/name_u].
Autumnal & halloween vibe names, that are two syllables or less please? For boys & girls.
