Conn, Andrew J., 62, b. 1838, Va Va Va; Rosa E., wife, 42, b. Mar 1858, married 24 years, mother of 7 children, 7 living, b. Ky Tenn Ky; John R., son, 17, b. Nov 1882; Jerry W., son, 14, b.

The children (other than Jacob) are all listed as born Ky Tenn Ky, which is inconsistent with the reported birthplace of Andrew. There is no son Jacob listed in the 1880 census, and his reported birthdate conflicts with that of Nancy, unless he had a different mother.
