Hello. My friend is sixty years old, and he has Alzheimer's. I only know his name as 'Bob.' Nobody I've talked to knows what his parents named him. Can 'Bob' be short for more than one full name? He needs a full name to fill out forms. He lost his driver's liscence and birth certificate. We don't know where to find his records! Please ask anybody nearby or say yourself if you know if Bob is short for anything else than Robert.
