Nathan Davidson Barnett was the brother of my great-grandfather, Levi Jasper Barnett. Both of these men are the sons of William C. Barnett and Charlotte Rose. William's dad was Joseph Barnett and his mother was Elizabeth McCartney. Joseph was the son of Zachariah Barnett and Lucy "Sarah" McCartney. Zachariah is believed to be the son of Thomas Barnett, who was born about 1745 in Germany. The only information I have about Nathan Davidson Barnett is a photo of his daughter, Mary, provided to me by a cousin. Anything would be appreciated. We have a Barnett website for this line and if anyone can connect, he can e-mail me at jebenstein@myfamily.com.
