So, here's a odd one, and might be a no-brainer, but I rather ask before doing something wrong. Anyway, I had a character idea that my character was adopted by a couple that wasn't his initial race. Is this considered acceptable within the lore, and if the character was adopted young enough where he didn't know his parents and his original name, would it be acceptable then that he'd have a name related to his adopted family's racial naming convention.
