I've got to quit doing this at night after a long day! Wrong family...not Davidsons... moved to NY and I am VERY sorry. Back in the 60s my aunt Helen Davidson Taylor did a lot of research. She sent me a copy of work done by Sarah Ragsdale Casey, with info from a Kay Dixon of N.C. whose father W.B. Williamson compiled a history of the N.C. Davidsons. by the Media Research Bureau of Washington DC. Mrs. Casey was from Texas, I believe, and was a descendant of Capt. Samuel Davidson of Rev. War fame." I never did anything with it til recently. This work was finished in 1958. John was m. to Mrs. Mary Morrison and the twins were born in Lancaster Co. PA. and moved in 1748 to Old Fort Rowan Co. (later Iredell Co.) N.C. I supposedly come from the twin Wm., his son John, his son George, his son Wm. , his son Richmon(d) James, my ggf. I am also a Davidson on my grandfather's side. Sometimes this gets a bit too much!!! I really appreciate your info.
