Radford was my great great uncle and Samuel my gg grandfather. My great grandfaher is Isaac (Ike) Adams lived in Knoxville Tennessee. I found Isaac's death certificate and it had Samuel Brooks Adams and his second wife listed as Issac's parents. Hopefully this will be new information for you. If you have additional data let me know. I have had no luck thus far finding Samuels parents. I would like to find the link back to Ireland, England or Scottland for the family. I have had dna testign very likely links our ancestors to the british Isles. My Haplotype is I21b.
Best Wishes Lowell Adams
