we have the name Guy for men.
Though 'guy' meaning 'man' comes from the name I think, not the other way around (a bit like the way Joe is sometimes used especially in the US). Guy, the name, comes from Guido - meaning 'guide'.
We also have people named after every single capitalized word in the English Bible.
There's a lot of place names in there. And depending on your translation some other random words get capitalised too. Desert, in Genesis 21 along with Beersheba - neither of which I've seen being used. Nor have I seen Kibroth Hattaavah (Numbers 11). So I imagine this was hyperbole?
