pioneer who did much clearing of land in his section of Ohio. The maternal grandparents were Jonathan and Margaret (Eberhard), also natives
of Pennsylvania, and early settlers in Medina county, Ohio. Grandfather Eberhard was a soldier in the War of 1812, and followed farming

Ohio, in I840, and his wife was born in the same state in I84I. Their
marriage was solemnized in I862. Mr. Hartman, who is now living retired in Ohio, a prosperous citizen devoted most of his active career to

membership in the American Medical Association.
