Peter Heinrich and his family were lucky, so their name was passed on: The earliest Herchenbach birth certificate available is that of his grandson Wilhelm :
By 1864, when Wilhelm's great-great-great-great-grand-nephew Peter Wilhelm was born, parts of the family had moved twice, first to the village of Eischeid (of which Peter Wilhelm's great-grandfather Heinrich Wilhelm had once been mayor), then to Neunkirchen. In each stage some Herchenbachs stayed behind, therefore even today some are still working on the old farm whereas others are running a restaurant in Eischeid carrying their name...
Peter Wilhelm, whose family lived in Neunkirchen, emigrated to the US in 1883, at the age of 19, sailing on the “America” from Bremen to Baltimore: To now, he is the only offspring of Peter Heinrich to emigrate as a Herchenbach and keep that name.
