I am searching a John Quilliams that married a Annie Clark. John was born abt 1810 and Annie abt 1820. They had a daughter named Cassie that married John Ellison and another daughter named Mary Maggie. They also had a son named Thomas born abt 1857. John and Annie are listed in 1860 Cocke Co census and also in 1870 census. In 1880, Annie is listed head of household. Would appreciate any help with this line as I have hit a dead end.
