I also have a Benjamin Riegel in my family.Benjamin was born around 1800 in Berks County Pennsylvania. He moved to Upper Dauphin County and settled between Millersburg and Berrysburg. My Grandmother was a granddaughter of his. Her dad was William Clinton Riegel. They house that he had built is still being used. I go there every so often to look around the graveyard. It is interesting. Hope to hear from you.
