According to my records Mary Agnes is the 2nd wife of Michael. I recently obtained the will of Johannes France (?-1786). His wife was Mary Agnes. They had six children all born after 1770.Attached to the photo copy of the will is acopy of a document detailing the "Account of Michael Roof and Mary Agnes his wife, late Mary Agnes France" The document is from 1792...I'm not sure when they married. Unfortunately I have not been able to find Mary Agnes' maiden name or her birth or death date. Hope that helps!
