Update to all this... with the help of several others, we've determined that Samuel Davenport was, most probably, the father of Samuel Edens. He was, indeed, involved with the East Tennessee bridge burning, and after fathering at least Samuel Edens (and perhaps Millard Fillmore Edens as well), he married Elizabeth Gourley and had 2 children with her, both of whom figured in my mother's life in some way. Samuel Davenport was later drafted into the Confederate armed forces, (Remember, he was sabotaging bridges for the union.. East Tennessee predominately supported the Union during the Civil war), and he was captured on July 4, 1863, at Vicksburg, Mississippi, refused parole (he would have been turned back to the Confederates, whom he wanted no part of), and was consequently taken to the Union prison at St. Louis, Missouri. He spent his last few months there, dying in September of 1863 and is buried under a confederate headstone at the national cemetery in St. Louis. His wife, Elizabeth Gourley Davenport, later received a pension by act of congress because of Samuel's involvement in the bridge burning. Thanks to everyone who helped me find out all this information.. the genealogical community is pretty awesome.
