he'll still have the same name as ur brother even if u give him a nickname. it'll feel weird deep down inside no matter what nickname you give him. just find another guy, one that doesn't have the same name as ur bro/dad.

if it bothers you, just give them a nickname close to their original name. i know people who ive never called them by their actual name. should be fine if you really care about this person
