Although it has been nearly 9 years since your message was posted, I am curious if you ever found the connection you were seeking between Sarah McHargue Ruark and Henderson McHargue? Henderson was a brother to my Samuel McHargue on my mother's side and Timothy Ruark Jr. was a brother to my Peter Ruark on my father's side. I have some info on both families--I am always interested in sharing notes. Please do let me know if you are still working on this family!
