Well, you say it's all Americans, but that raging prick Jacob Reese-Mogg named his latest child Alfred Wulfric Leyson Pius Mogg, and I was once on a training course with an Irish fella called Clen Sten (pronounced Cleen Steen).
I also, genuinely (have mentioned it several times on CaB in the past) worked with a chap called John Schitte (and it was pronounced Shit as well), although his parents were German, where Schitte is a very common surname and, of course, doesn't mean shit, so I suppose that one doesn't really count.
