Seeking data on Isaac Kerr who married Ellen Perkins 2 Nov 1854 in Lawrence Co MO. They had daughters Mary J., Louisa, Martha, and Tennessee. The family appear on the 1860 census in Greene Co MO. On the 1870 census they are listed as Issac Carr, living in Benton Co MO, Alexander twp. On the 1880 census they lived in Benton Co MO, Alexander twp, listed as Issac R. Kerr. Unable to locate then on 1900 census. Any info you can give me will be greatly appreciated. Thanks in advance. Ruby
