Thanks, Doyle. Somewhat of a mystery. Both gravestones can be seen on Find-A-Grave. Just type YELL into the last name box, select UNITED STATES, ARKANSAS, and JEFFERSON COUNTY. He and his father are the only two that will come up. In Mansfield, type YELL into the last name box, select UNITED STATES, LOUISIANA and DE SOTO PARISH.
