I mean, Person of Interest has Joss Carter. Stargate SG-1 has Sam Carter. Agent Carter has, y'know, Peggy Carter (the clue's kind of in the name on that one). Then Doctor Who fandom has this vlogger.
To quote someone (whose name, fortunately, was not Carter*), "I can't stand the confusion in my mind!!!"
*His name was Stein. And he was played by Rodney Bewes.
