Joseph Frederick m. Mary Crubaugh in PA 1796/7
I'm a descendant of Mary Crubaugh's younger brother, John.I'd like to exchange info on Mary's father, Jacob, and her grandparents for info on the descendants of Joseph and Mary.Jacob was born in Germany in 1731 and immigrated through Philadelphia in 1749. My chart of approx 3000 descendants of Jacob, doesn't include much on Mary's branch.
