I personally do not like that spelling of Jaxson AT ALL.
Jackson looks slightly better, but I'm not much of a fan of -son endings,and prefer plain old
Jack.
Gabriella and
Ariana are both pretty, I'd lean towards
Ariana. I dislike
Miranda, and find it a little dated. Not sure if you're pronouncing Daylan the same as
Dylan or actually with the "DAY", but either way it looks the same to me as Jaxson,
Dylan is much better.
