I can maybe help a little... I grew up on Wharncliffe, and I'm in the process of helping my buddy Mike Dingess with his geneology.
His grandfather James Dingess was a brother of John. According to Mike's mom, their father's name was George. That's all I've got for you. I just posted a message up top hoping to find more info. Keep an eye on it, since it pertains to you too.
