The Reunion that is held at the Hermitage is for the descendants of Andrew Jackson,Jr. who was one of twin sons born to Severn & Betsy (Rucker) Donelson, my ggggrandparents. He was adopted by President Andrew & Rachel (Donelson)Jackson because they were unable to have children of their own. Rachel was Severn's sister, & both were children of Col. John Donelson, co-founder of the city of Nashville, TN. I have a listing for three different Daniel Smith Donelson's and 1 died in Knoxville, TN on April 17, 1863. I want to direct you to the book "Notable Southern Families, Volume II" by Zella Armstrong. It contains most of the Donelson/Donaldson family & can sometimes be found in Public libraries &/or archives. I have a hardback copy and know it has been reprinted in paper-back. Maybe you'll be lucky enough to find one!
