Asa's parents were John Matson and Nancy Ann Clevenger. Dortha's parents were Aden Clevenger and Sarah Beadles. The Matson and Clevenger families lived in Frederick County, VA before settling in Clinton County, Ohio. My information on Mary's parents and grandparents comes from the book Clevenger Pioneers & Descendants by George R. Griffiths. I haven't been able to find additional information on John Matson so far.
