I am searching for additional information on a Sarah Tinney, b. c. 1823 in South Carolina [according to 1850 census]. Sarah is the mother of Elizabeth Jane Tinney born out of wedlock c. 1842 in McMinn Co., Tennessee. The father was Thomas Edward Cox who raised the girl. Elizabeth Jane Tinney married William A. Joyce in 1866.
Sarah Tinney appears on the 1850 census in McMinn Co., Tennessee living with Isaac Tinney, b. c. 1785 in South Carolina; Isaac Tinney, b. c. 1829 in Tennessee; and Lucinda Lanson/Lawson, b. c. 1825 in South Carolina. Is Sarah one of the children of the elder Isaac Tinney? The two Isaac Tinneys next appear on the 1860 census in Edwards Co., Illinois.
I cannot find out what happened to Sarah after 1850 however.
