By Robert Morriss giving away by Deed all of his furniture and items to keep house in the 1850's to his niece and sister of Anzoletta. Also his wife, Sarah dying at the home of James Beverly Ward in 1861 makes me believe that both were convalescent and unable to care for each other especially Robert Morriss.
All the years that Robert Morriss stayed at his nieces home of Anzoletta there is no one saying anything about meeting Robert Morriss or of him ever saying anything to anyone. RM could have had an early stroke before his wife's death. He may have not been able to talk, do or say anything at all.
That may be the reason that James Beverly Ward had to make the arrangements for her funeral and pay for the funeral himself. Also Robert Morriss left no Will, rich as he was he had no possessions and while staying at Anzoletta's home, according to court documents she and her family were poor during the Civil War.
If Robert Morriss had so much and had a story of treasure to tell surely he would have told his loving niece, Anzoletta...
Also James Beverly Ward lost Hunter's Hill Plantation in 1870 over debts he owed totaling over eight thousand dollars. All of his lands, his two saw mills, slaves, furniture and farm equipment was not enough to compensate for the amount owed.
He needed money as he and his family were staying with his daughter at her home in Lynchburg. JBW was a surveyor after that to make a living.
He most likely felt he could write a good treasure story.
