I had a classmate from elementary through high school whose full name was Lieutenant George (70’s-80’s). I’m guessing his parents never wanted him to be considered just enlisted, or maybe they were huge fans of Columbo. I have never met or heard of anyone else with the first name Lieutenant.
I always thought that was a cool name. I cleaned up at Trivial Pursuit back in the day, in part, by answering, “Thor Heyerdahl” to any question regarding both exploring and sailing.
I knew a guy named, 'Ellwood Cridge", which I also thought was a great name. Sounds like it would be the name of a Scooby-Doo villain, or maybe the name of the Tall Man in the, “Phantasm” movies. Figured if I ever wrote a book, I’d find a way to use that name.
Quite possibly, the apostrophe got inserted just to cause other people to pronounce it the way they preferred.
I knew a guy once named DicKard, with the accent on the second syllable. I suspect that he spelled it with the capital K just to get people to say it that way. If it were written Dickard, how would you most likely pronounce it? (He said the name was derived from the French name DesCartes.)
ETA: In the early early days of computer graphics/animation, there was a prominent player named Stan VanDerBeeK. Rumor had it that he capitalized the final K just for the symmetry of it.
There was a story on the news last night about a police officer who saved a guy on the RR tracks. They never showed her name on the bottom crawl, so I don’t know how it was spelled, but her last name was pronounced “Urea”.
