Im looking through old papers that my g.father Daniel Benjamin Hamill,Jr of Chattanooga had when he was researching our lineage. Sounds like youve got the same info as me. Not sure though.John J Hamill was my great great grandfather and he had a brother Milo Smith that married Anna E, according to my papers. Their parents Daniel Best Hamill and Mary Jones.
Let me know if this is familiar to you I have lots of papers I am try to read through.
