Junior is also sometimes used as a given name.
I went to school with a ol' feller (named after his father) who had the misfortune of having the name Junior Surname deleted Jr..
So, of course, he has gone through life being called "Junior Jr.".
Good gravy, what were his parents thinking.
I wouldn't do that to a kid for no man's money.
LOL. My grandma married after grampa died. My step-grampa had a son whose name was Junior JR too. Western North Carolina.
