Well, I know a lot of older adults whose full names are simply Jim, Bill, etc. Just like I can think of little girls today whose parents have named them Rosie and Gracie. Perhaps some filled out their nickname rather than their full name, but there were certainly others who were never called anything but Jim, even on the birth certificate. :)
