When I lived overseas (Laos) in my teens I knew a guy named Rick Shaw and a girl named Libby Glass.
A perfect reason why you just can’t disallow crazy names unless you can prove that there is no one living at the address provided.
When I was in college at UC Berkeley, I had a sorority sister who used to “collect” unusual names. (She worked in the registrar’s office.) The one I remember the best was “Mary Beth Overfelt”. Poor girl was blackballed from more than one sorority just because of her name (considered scandalous in the ‘50s). All the girls whispered that it was lucky that she was a girl ‘cause she could get married and lose that unfortunate surname. :^) I’m sure that she was probably very nice and not a “round-heels” at all.
