Theodore R. Gilleland, teacher in the intermediate department of Cartersburg graded schools, is one of the oldest teachers in Hendricks County. He was born in Indianapolis, Ind., Sept. 6, 1846, the only son of John O. and Nancy J. (Pope) Gilleland, and grandson of William Pope. In 1851 his parents moved to Hendricks County, where, in connection with working at his trade (plasterer), his father engaged in farming. He attended in his boyhood the district schools, and later, the Belleville Academy, and in the spring of 1877, a term at the State Normal School, at Terre Haute. He commenced teaching in 1868 and has taught nine years in Belleville, five years in Brownsburg and three years in Cartersburg. He has been a successful disciplinarian and instructor and has a reputation second to none in the county. In addition to teaching he carries on a small farm on section 31, Liberty Township. He was married Feb. 26, 1874, to Amanda M. Wilson, of Danville. They have two children--Daisy I. and Raymond I. Mr. Gilleland is a member of Belleville Lodge, No. 205, I.O.O.F.
