Isn't Max usually a nickname for both masculine and feminine names? Like a person called Max could be Maxwell or Maxine. Like right now one of the new protagonists in Stranger Things 2 is a girl named Max.
It could be, certainly. Partly I was evaluating this as a question about full names only. And more importantly, Maxine has only recently re-entered the top 1000 at all and is ranked at #874. Max- names for boys are vastly more popular.
That's true––I'm not a fan of Maxine either. I do know some girls named Max, but I don't think I ever heard them use a full-name version like Maxine though. So maybe it was just Max.
