John & Rick, You were looking for Rial Barnett and wife Mary A. Austin. Mary was Rial's second wife. He first married Elizabeth Barham in 1845 at Greasy Creek, Dallas Co. They moved to Marion Co, Arkansas where she died in 1861. they had five children. Rial moved back to SW MO and in 1865 married Mary A. Austin at Greasy Creek. Rial and Mary had nine children. In the 1880 census, they are in Polk Co, not Dallas Co. If you need more on this line, let me know. Jerry
