My Mother, Lorraine E. Dunnam, married Earl V. Johnson Sr. abt. 1940. Her father, Sidney Ethel Dunnam. Her Grandfather, Sidney Edward Dunnam. I have one of them in the Texas Census for 1870 and 1880. This is in line with family stories about East Texas. I have more on the Dunnams that left Texas c. 1930 for California. I hope this is of some help.
