Younger sibling for August??

My first son’s name is August. We liked that it’s familiar and easy to spell and pronounce but feels a bit vintage and romantic (imho). I know it’s gotten trendy recently but that doesn’t bother me.

Now we are having such a hard time deciding on another name. Please help me lol! What would you name a little brother or sister in this case?

Other names I like but husband doesn’t are Ansel, Asher, Juliet, Jane, and Mary.

Names he likes but I’m not sure on are Aaron, Andrew, Sophia, Daisy.

Thanks!!
