My records show that Daniel Siverling Jr. married Catherine Mary Straw (my great-grandaunt) in Venango twp, Crawford Co., in 1833, and they had four children: Thomas, b. Venango twp 1835, George (Washington?), b. 1838 Venango, Leander M., b. 1840, twp unknown, and Catherine, b. 1848 in Hayfield twp. His father was, of course, Daniel, Sr. Her parents were Philip Straw & Leah Gehr. Contact me off board if you wish more information.
