According to legend, Andreas was a priest, but didn't feel he was suited for the position. His father, Ludwig Kessinger, was quite wealthy and it was traditional for at least one son to join the priesthood. So Andreas left the Church and all his father's wealth, took Johannes, supposedly a former nun, as his wife, and they set sail from Belgium to America on the White Line ship Catherine. Supposedly the Kessinger family owned considerable property, including a castle or two on the Rhine and/or Ruhr Rivers. I received one "history" that said the family originated in Essen, Germany and that they were a family of singers, thus Kessensingers. But the word for singer in German is NOT singer! But they may have been from the Essen area for it lies in the Palatinate.
Some descendants living in America wanted to return to claim their wealth, but World War 1 took care of that dream.
It was pure luck that I found their names on the ship's passenger list in the first volume of Pennsylvania Pioneers (by Ralph Strassburger) I opened. Their signatures as well as their names typed for clarification appear.
