Kenneth, Unfortunately, I can't answer any of your questions but perhaps you can help me. Mary and Sarah Patterson, daughters of your Samuel and Mary, may have married two McGaw brothers, John and William. Can you confirm? I am tracing McGaw line. Mary Patterson who married William McGaw 5 Oct 1775. Sarah married John McGaw around 1777. Mary was born about April, 1757. Later in history, John B. McGaw married a Jane Patterson in Warren County, IL 29 Jan 1856. One of the McGaws moved from SC to Ohio and IL. I believe some Pattersons moved also. Thanks in advance.
