I don’t think it is too cutesy at all. It seems to be a well matched set that would all age well. They all have a classic elegance to them without sounding dull.
I love this sibset. I think all the names flow well and I love how classic they are. I also really like [name_f]Charlotte[/name_f] [name_f]May[/name_f].
The sibling set isn’t cutesy at all. It leans more towards trendy classic. The only thing I would change is the [name_f]Annabelle[/name_f] spelling. I prefer [name_f]Annabel[/name_f] because the -le seems unnecessary to me and a bit frilly.
[name_m]Ah[/name_m] [name_f]Grace[/name_f] is everyone’s name or nickname starting in the 2000’s here. [name_f]May[/name_f] sounds refreshing! Like your names!
