Atticus vs. Alonso / Alonzo
Can't decide between Atticus and Alonso/Alonzo (can't decide the spelling there either). I have some concerns with both names. Is Atticus too linked to "How to kill a mockingbird"? Also we aren't of Italian, Spanish or Latin descent is it therefore weird/inappropriate to use the name Alonso/Alonzo? Name ideas/inspirations are much appreciated. Thank you !
