Butler, and General George H. Morgan. Generals Butler and Morgan both served as Attorneys General for Tennessee's 5th Judicial Circuit. Engineer T.H. Butler's work in the field of civil engineering involved road and highway construction, bridge building, and land surveying. In March 1854, "An Act to incorporate the Lafayette, Rome, and Lebanon Turnpike Company" by the Tennessee 30th General Assembly was passed into law in which T.H. Butler was named among "a body politic and corporate to open books and receive stock for the purpose of constructing the Jennings and Line creeks turnpike road [State Route 56] from Gainsboro' by the nearest and most direct route to the Kentucky State line, in the direction of Tompkinsville, Kentucky" and "to bridge Line and Jennings creeks on the line of said road." Years later in March 1860, "An Act to charter the Granville and Martin's Creek Turnpike Company" by the Tennessee 33rd General Assembly was passed into law which appointed T.H. Butler as a Commissioner for the purpose of locating the route upon which the Gainesboro and Defeated Creek Turnpike (State Route 53) would best be built, "to survey the two routes from Gainsboro', by the way of Flynn's Lick, to ... Smith county." In 1870 working with fellow surveyor William Gore, T.H. Butler was instrumental in helping establish a new county in Tennessee, namely Clay County. Butler's engineering skills would eventually aide him in his turnpike and railroad-oversight roles as ex-officio Internal Improvement Commissioner and as a Commissioner of Railroads while serving as Secretary of State. Family T.H. Butler's first wife was Mary "Polly" Gore (1822–1851), a distant relative of U.S. Vice-President Al Gore. According to Susan Butler's family Bible, Thomas and Mary were married July 2, 1844, and "their issue are Mary Ann, William Bailey, Mounce Gore and Sarah Ellenor." Butler's second wife was Sarah Ann Holford (1834–1900), and they "were married 14 April 1853 and their issue are Lizzie Loucetta, John Franklin, Bowen Butler, George Grundy, Martha Jane, Dixie, Rosa Lee, Thomas Harvey, and James Wash, Sam Stone." T.H. Butler was born in Clay County (then Jackson County), Tennessee, the son of Colonel Bailey Butler (1779–1842) and Sarah "Sally" Scanland (1789–1828). On July 4, 2003, the Tennessee Historical Commission dedicated an official historical marker in their hometown of Butler's Landing which the Butlers founded. T.H. Butler's pioneer father and their family are honored on one side of the marker,
