Children: i Donald Gene Adkins b. 24-Oct-1932. REMARKS: no one seems to have the exact date of the birth of Almira Farrel. There is also a conflict in the spelling of her last name. i have adopted what seems to be the majority view, also the more common way of spelling the name. But I should say that on the sheets returned by Mrs. Gilles and Mrs. Moore they have carefully indicated that it is "Ferrel."
