I may be years too late, but the William Allen mentioned is my fourth great grandfather. His second son, William, is my third great grandfather. His son Fredrick Thomas homesteaded in Missouri with John Clinton Barrett and others. Fredrick had many children, my great grand father Hugh Columbus Allen being one of them. This branch of Allen's from the original family of Hawkins TN is still settled in Missouri (most of us within 200 miles of Fredrick's first homestead), specifically the hills of the Ozarks, geographically very similar to the Hawkins region of TN. My father is a James Allen, as am I and my son. Barrett's and Allen's were still tight as of the 1930s in this area, but no links today in this region. Interested in any information that may be available prior to the Allen's before TN.
