Thomas Goode Clark was born in Kentucky ca. 1815. In the mid 1840s, Clark and his wife Margery B. Rogers Clark (b. in Tennessee on January 9, 1822), moved to Sarepta, Calhoun County, Mississippi with their sons Jonathan (b. in Kentucky ca. 1842) and Albert Henry (b. in Kentucky ca. 1843). T. G. Clark made his living as a farmer, and by the time of the Federal Census of 1860 the family included six more children, all born in Mississippi. T. G. Clark served as Captain of Co. F, 42nd Mississippi Infantry, while his two oldest sons, Jonathan and Albert Henry, served in Co. F as privates. The 42nd Mississippi suffered heavy losses at the Battle of Gettysburg, including 62 killed or mortally wounded, and 13 more who died as prisoners. Among the dead were T. G. Clark and his two sons. Margery Clark continued living on the family farm with her remaining children after the war, and was still a resident of Sarepta when she died in 1917.
