The term Pennsylvania DUTCH is a corruption of the word DEUTSCH meaning German. All you have to do to "be Pennsylvania Dutch" is to live in that state and be from a German-speaking group; i.e. from one of the early Germanic states such as Hesse, Prussia, or Switzerland, or Alsace, etc. While it is true that many of the Pa Dutch settlers sailed from Rotterdam, that was just the nearest port for them. Very few Netherlanders settled in Pennsylvania. My family always said anyone with a German accent spoke "kind of Dutchy." Also used for children who were still lisping or using baby talk. Double Dutch is when they turn the jump rope really fast! Jan Hall Pa Dutch on both sides, so maybe I'm the Double Dutch.
