Am looking for information and documentation on the marriage of Joseph Sullivan Cox and Mary Priscilla Glasscox (possibly Mercer Co., Missouri). They are both buried in Evergreen Cemetery, Lineville, Iowa. Joseph was born January 20, 1837, died August 10, 1909. Mary was born November 29, 1847, died November 1, 1904. Also looking for information on their children, if any. Any help would be greatly appreciated!
