Richard,
There is also a book on the descendants of Thomas SCOTT of which your grandmother is a descendant. It was privately published in 1975 in Greenwood, IN. I don't have the exact title here at work, but will list it on this thread.
My wife is also a descendant from Al McKinley and I've recently started researching the BOW family. Darla also listed some good information concerning the SCOTT line.
