Advice/Options Please!

1.) Do you guys see Blair as a baby boy or girl name? I’m in the US, & to me it’s a girl name but I guess it’s primarily a boy name?? 2.) Baby boy name suggestions for siblings named Ezra & Kai? (Both boys). We’re waiting until birth to find out the gender, we have Blair picked for a girl & would love boy suggestions! They just can’t start with E or K (I’m weird about matching initials) ETA: feel free to give girl suggestions as well!
