He was probably the son of Jonathan Lounsberry or possibly Matthew Lounsberry, who moved from Tioga County, NY to Menard County, IL in 1832. The 1850 census of Menard Co. will list them, along with their wives and children. Their parents were Matthew Lounsberry and Mary Wagon. They are listed on the 1820 census of Tioga Co., NY. The Menard Co. Historical Society has published cemetery records, which should have all of these people.
