Although the Walters book gave Rhoda a death date of 19 Jan 1899 - I believe that to be very wrong. She was not with Rufus in 1880 - he was living with their son George and had a much younger wife named Ellen and stepchildren with the surname Ford. I believe she died before 1880 and Rufus King Walters remarried.
Rhoda CAWTHON and Rufus King WALTERS were married on 31 January 1839.205 Rufus King WALTERS, son of Robert WALTERS and Nancy PAYNE, was born on 2 August 1813.205 He died on 9 January 1890 at the age of 76.205
Rufus K. Walters married Rody Cawthon on 31 Jan 1839. Rufus and Rhoda were 2nd cousins; they were both great grandchildren of Robert Walters & Joannah McBee.
