William,
Have you had any luck? I'm working this line as well, and I've seen someone post (below) showing John EUBANK and Elizabeth RAINES as his parents. There were no references and you had to create an account to communicate with the contributor, so I didn't. Haven't looked in to this John EUBANK yet, but I will.
Drop me a line.
