I used to work at a Credit Union and one of the customers name was FUCH.......pronounced Fush....
Another customer who grew up with the surname COCK, when he applied for a loan, he had a certificate showing he had changed his name by deed poll from that to something else.
I asked him about it, and he said, he grew up copping shit from people and he did not want his kids to have the same thing happen, hence the name change.
