Everyone in my family has a "full" legal name, but many nicknames that start in childhood that follow them throughout adulthood. Most of the nicknames are not even related to their real names! It makes me wonder where some of them came from. However, it is a common tradition to be named after a relative. Someone could be called Joseph, but nicknamed Bob. Everyone knows its not his real name, but no ever calls him Joseph. Not even Joey, nothing that makes sense.
