DAVID HEFNER, farmer, P. O. Lima, was born in Berks County, Penn., June 22, 1804; son of Isaac and Susannah (Worline) Hefner, pioneers of Ross County, Ohio. His father died in that county, his mother in Perry Township, this county. From twelve years of age our subject was reared in Ross County, where he received a limited education in the common schools. He was married, in April, 1828, to Frances, daughter of Daniel and Christiana (Strausser) Frederick, natives of Pennsylvania, and early settlers of Ross County, Ohio. The issue of this union was nine children: Susannah (wife of John Gillespie), Amos, William, Mary, Sarah (wife of Levi Brentlinger), Albert, Isaac, Jane (deceased), and Rebecca (wife of David Worline). Mr. Hefner settled in Perry Township in 1840, locating on the farm where he now resides. His farm comprises 320 acres of land, all of which he has cleared and improved. He is one of the leading farmers of Perry Township, and a worthy citizen. He and his wife are members of the Christian Church. He cast his first vote for Andrew Jackson, and has always been a stanch Democrat.
