Joe, Other than a land deed that mentions a William and Mary Mcguire,is there any other information that would make a Mary married to our Revolutionary William McGuire ? I'm not home where I have all my information, so I don't know which land deed it was ,or when.I'm still up in W.Va. I do know that there was a younger William McGuire in Tazewell that was married to a Mary/Polly Bruster. I have thought that he may have been the one on this land deed. He would have been old enough to buy and sell land. I also think he may have been the son of Joseph McGuire,our William's brother.
