Isaac Lafayette Hill, soldier, settler, and legislator, the son of John Hill, was born on February 1, 1814, in Jasper County, Georgia. In 1834 he traveled to Texas with his uncle Asa Hill. Isaac taught school in the Cole settlement in Washington County before joining Company D, First Regiment of Texas Volunteers, as a corporal under the command of Capt. Moseley Baker. He was in command of the ferry at San Felipe during the retreat of the Texas army in April 1836 and subsequently fought at the battle of San Jacinto. In 1845 Isaac settled near Round Top in Fayette County, where he became a prosperous planter and slave owner and represented that county in the Senate of the Fifth and Sixth legislatures (1853–57). In 1863 Hill paid an unknown substitute to serve in his place in Capt. Zebulon M. P. Rabb's company of the Plum Grove Rifles, a Home Guard unit. He later served as a private in Capt. James C. Gaither's company, the Round Top Guerrillas, organized by Brig. Gen. William G. Webb as a volunteer cavalry "to repel armed or hostile invasions of the state." Hill was married three times and had nine children. During the 1870s he was a promoter and stockholder of the Central railroad. He died at his home on July 18, 1889, and was buried near Round Top.
