Move to the rural south and he’d be popular
Move to another school district or continue to homeschool. Why would the parents put him right back into the same situation? Changing his name isn’t going to do anything but egg the bullies on further by showing how weak he is. He may very well have been a weak kid from the start who is a prime bully target and this has very little to do with his name. Bet there are Bush, Clinton and Barry names at the school and none of them bring on bullying.
