In Japanese, I know you refer to your older sister as お姉さん and older brother as お兄さん. Something along those lines!
But I have 2 older brothers, and I want to change their contact names to Japanese, like "Joshua" to "お兄さん".
Both my brothers are similar in age, so to avoid confusion what would I change both of their contact names to? If I were to change them both to お兄さん, it would be hard for me to distinguish them. So what should I put?
