Robert Hanna

Robert Hanna Jr. (April 6, 1786 – November 16, 1858) is best known as one of the forty-three delegates to the 1816 Indiana Constitutional Convention and Indiana's third U.S. Senator after it achieved statehood in 1816. A native of Laurens County, South Carolina, he settled in the Indiana Territory shortly after it was established in 1800 and began his long career as a public servant in Brookville, Indiana. Hanna served as the first Franklin County sheriff (1809–20), as a brigadier general in the state militia, and as the United States General Land Office registrar in Brookville and Indianapolis (1820–30). Hanna was appointed to fill the vacant seat in the U.S. Senate following the death of James Noble in 1831. Hanna served in the U.S. Senate from August 19, 1831, to January 3, 1832. After his return to Indianapolis, Hanna represented Marion County in the Indiana House of Representatives (1832–33; 1836–39) and in the Indiana Senate (1840–41; 1842–46).
