Mary Polly Decker and Gottlieb "Caleb" Blackwelder
I am searching for info on Mary Polly Decker b.1700 in Germany who married Gottlieb "Caleb" Blackwelder" b.1700 in Germany. They had a son Gottlieb "Caleb" Blackwelder b.1722 in Germany who married Elizabetha "Betsey" Pfeiffer b.1724 in Switzerland.
Does anyone know anything about Mary's parents or ancestry?
