I believe we may be distantly related. Was your g-grandfather Seth Cole that married Melvina Samantha Lemons? Did your father have siblings named Alwilda, Annetta, Rovena, Fay Vera and Theona? If this is your line I don't have much on the Coles but I have been researching the Lemons line for 20 years and have lots on Melvina's family.
Look forward to hearing from you. Please email me at firstname.lastname@example.org
