Hello, I am a descendant of Antoine Schimpf, one of the brothers of Pierre Schimpf (Petrus Raimundus) born in Büchelberg, Pfalz. Their parents were Johann Schimpf born 1718 12 22 in Schaidt Pfalz and Reine Kopf Johann's father was Johann, and his father was Laurent born ca 1660. Do you have certainty about Pierre Schimpf b and d dates? Kindest regards Jean-Marie Schimpff (the second f came when Antoine migrated to France, Schleithal, near Altenstadt where Pierre settled). Pierre's wife was Regina Getto. There is a mistake with his mother, Regina Kopf, in US genealogies.
