There is a Joseph Peter Raaskopff, son of Mattias & Angela Raaskopff, who was baptized on 22 July 1715 in Wittlich, northeast of Trier, in what is today Rhineland-Palatinate. A Peter Rosskopf immigrated to Russia, arriving in the colony of Volmer on 18 July 1766. He is recorded there on the 1767 Census in Household No. 41.
I was not able to locate other corroborating members of this family in Wittlich, such as his wife or the birth of his eldest son Joseph (per the 1767 Census). If others are able to corroborate other pieces of this family's information in Wittlich or some neighboring village, please notify the webmaster.
