Thanks for the reply. I've seen reference to James' wife being Mary Harmon but I have not been able to locate a marriage record to confirm that her maiden name was actually Harmon. I haven't found a son named Jasper in census records. I am missing 1860 though. Can't seem to locate John and family in that census. I'm guessing Jasper is a son by his second wife, Mary Couch. Based on the 1880 census John and Mary had a son named John, which is interesting since he already had a son named John with his first wife, Ann. Below are the children I show for John Lea based on census records.
Laura Lea 1834 Alfred A. Lea 1837 Joseph U. Lea 1839 Emeline Lea 1841 James Lea 1846 Tennessee Lea 1849 John Lea 1852 America W. Lee 1853 Margaret Lea 1857
