I have corrected many of the numerous problems with the profile of Lewis Green, b. 1724. His parents are still demostrably incorrect, but I edited his biography to be consistent with what is known. He is not Lewis "Bear" Green. I moved the 8 children that were descended from the Clinch River "Bear" Green over to his profile. Previously, Wikitree did not have profiles for Lewis Green III and Lewis Green IV ("Bear"). They now exist and the biographies reflect what is known based on primary source data. The place to start is the monumental, well-researched genealogy "A Genealogy of Lewis Green and Associated Families" by Judy Parsons Smith, available for download (as Windows into our Past Vol 6) at this link:

I have not looked at Massey Greeen at all. I do not believe there is anything to connect her to either of these Lewis Greens.
