I have a photocopy of a 1930 letter written by Earle Human in Toledo, OH to Campbell Watts addressing his "aunt and uncle and all" who were living in Detroit, TX. Campbell was the son of Daniel C.R. Watts.In 1930, Earl W. Human was living in Toledo as well as a Charles Human (b abt 1899 TN). Also, there was a Campbell E. Human in Cincinnati, OH Ib. abt 1910 in TN). Are all of these from the Mary Jane Lewallen and William Riley Human?
