Thanks for your quick response! I am from George and Anna by way of their son Thomas Jefferson Johnson (b. 1844) and his son James Nimrod Johnson (b. 1874), whose daughter Eunice Elizabeth Johnson (b. 1905) was my great-grandmother.
Eunice's baby sister, my Aunt Juanita (Nita) died this year at age 89 -- she was the last of nine children born to James N. and Telola Stewart.
