I read a theory that the reason serial killers so frequently seem to have the middle (or sometimes first) name Wayne is because they often had authoritarian fathers who admired John Wayne. Don’t know if that makes sense but maybe there is no better explanation.
you mean they didn’t name their sons after Wayne Newton?
Since he was born in 1933, I doubt it. Wayne’s acting career had started by then, but he wasn’t the sort of household name you name your kids after. Even by John Wayne Gacy’s birth (1942), I still doubt anyone would immediately identify “John Wayne” with masculinity. (”Stagecoach” was Wayne’s main starring role in a hit movie at the time.)
