Help with spelling for babies name!?!

We were going to stick with an "A" name because our daughters name is Addyson. We were going to pick either Austin Gregory or Ashton Gregory. Grandpa loves Bo Gregory....(it's kinda growing on us) but the spelling is driving me crazy! I strongly dislike the spelling "Beau", & kids are so mean these days if we did Bo they would make fun of him and call him B.O. (Like he smells) & Bow.. I don't know!!! Help!!!
