I am a fan of traditional spellings.

DD2 is Marley. And TBH, I really REALLY wish I had spelt it Marlee. For this kind of name (Ashley, Marley, Bailey) where it is so androgynous, I can totally understand the need to make the name a bit more obviously feminine. Bailey is a traditional spelling, but traditionally the name was masculine.

I prefer your Baylee. It is not like you are taking 'Natasha' and turning it into 'Naytarschya' just for the hell of it.

FWIW, my DD1 is 'Charlotte' - you would not believe how many times I have to spell THAT to people. O_o
