George Ridenour being one of the first settlers of this county endured many hardships and privations, and the circumstances of the times gave to his employments a somewhat versatile complexion, as he was a cooper, a maker of coffins, tooth extractor, better of broken bones, etc., etc.; he died at the age of eighty-four; his widow still resides on the home farm, and is now in her eighty-fourth year. Our subject was never married. He became owner of land by the death of his father.
