That's true. It does ring a bit odd for the 1950s. It would be like having a female character named Madison or Taylor set in the 50s. You never
heard the name Madison for girl until the early 80s after the movie Splash came out, and Taylor didn't come into prominence for girls until the 1980s either.
To this day, I HATE the name Taylor for a girl because it evokes the wholly masculine image of Charlton Heston running around in a loin cloth in Planet of the Apes. Taylor the astronaut/human ape.
