"WILLIAM H. MANTLE was born in Pickaway County, Ohio, May 13, 1841, and is one of the eight children of SAMUEL and RACHEL (LUSADER) MANTLE, their names being ISAAC, BALSON, MARY, MATILDA, ALEXANDER, WILLIAM, MARGARET and JANE; of these, the first two are deceased. The father of WILLIAM was of Dutch descent, was a farmer the greater portion of his life, and died in Pickaway County, Ohio. When WILLIAM was young, his parents removed to Franklin County, Ohio, thence to Benton County, Indiana, Vermillion County, Illinois, and again to Benton County, and later to Tippecanoe County, Indiana. On April 26, 1871, he was married to MARGARET A. WATSON, by whom he had two children, one surviving - JOHN. In April, 1872, MR. MANTLE came to his present location, seven miles southwest of Wolcott, having a cultivated and improved farm of 320 acres. His principal porducts are corn, hay, wheat and flax, but makes a specialty of cattle raising and dealing, together with hogs and horses. MR. MANTLE is an upright and self-made man; he began life without the means, but by those great factors - industry and economy - has risen to a position of independence and comfort. MR. MANTLE is a well-respected citizen and a genial gentleman."
