Hi, I've been reading a book, Ancestral Trails by Zorbaugh, that says that Priscilla Evans Phelps was the maternal Great-Grandmother of Robert E. Lee. I have searched for more information on this unsuccessfully. How can I find out if this is true? She was at one time married to MacClain Phelps. I do not know if she remarried. Thanks for any help you can give. Renee St. Louis
