Sorry I didn't see this message for such a long time, it's difficult to see the message notification on here. Most of my relatives live in the Cincinnati/Northern Kentucky area, so I wouldn't be surprised to learn of any Runyans further up, but don't know of any specifically. My dad is actually a Tom Runyan, but he never worked in a rubber hose factory!
Did you ever have any relatives in the west central ohio area? I used to know a Tom Runyan that worked for a rubber hose factory.
