We're talking about Texas Cherokees, instead of Civil War, but "what the heck!". Ken and I are double first-cousins, so we have identical ancestries except for our mothers and fathers (Martin brothers married Lee sisters). Our Fields ancestry comes through our mothers, but we're also descended from the "Downing" Cherokee family through our fathers. The progenitor was "Major" John Downing and we descend through his daughter, Nannie or Nan-yehi. World's getting even smaller, huh?
