I am searching for informaation about my great grandparents. I am having trouble locating them prior to 1880. I know one was born in Tennessee and the other in Kentucky. They end up in east Texsa in 1880. Was there a certain route or trail or something they may have taken during this time period? How should I go about looking for their most probable migration route to Texas? I cannot find anything on them in Tennessee or in Kentucky. Any suggestions are appreciated.
