I have a possible link here. Benjamin and my Matthew Greentree may possibly be brothers. They are from the same area, and there weren't that many Greentree's around. Also, both Matthew and Benjamin fought in the Revolution. Another interesting tid-bit - Matthew's son, Matthew, b. 1788, moved to Brown County, Ohio when he was a young man, and with him was an older lady, Margaret Greentree. He was in his 20's, Margaret about 45-50, most probably Matthew's mother.
