I do not have info on sarah ellen but Michael Fonkennen b.1760 was married to Margaret Comfort. Their child Joseph, b.1793 d.1875 married Anna Mary Poorman. There were several children from this marraige including Mary Ann who married Joseph Kuhn. She would be my great-great grand mother. Joseph changed the family name to Foncannon. Michaels father was Johan Jacob von Kennen. b.5/6/1731. I hope this helps some.
