I was named after "anyone", but I'm not sure just who. My father was named after his uncle, and was always uncomfortable with the fact; it's far too late to ask him why. He insisted on a name for me that was distinct from anything in the family. My parents looked through a newspaper listing of recent draftees, and he found and liked the name "Delton". If you google that, you'll find a number of places and a very few people.
By about the halfway point in my life (so far), I was getting really tired of telling people my name, and having at least 80% of them mis-remember it, so I shifted to use of my middle name when I went into a new setting. I've found it a marked relief to have most people get my name right.
A couple of years ago, the local paper reported the death of an unrelated "Delton" in the next village down the road. He was a veteran, of about the right age. The odds may be a little long, but nowhere near as long as if he had been named Jim.
