I do not have any information about my grandfather, John L. Hefner. He divorced Juanita (Daisy Mae) Hefner in the mid 1920's. They had one child, my father Robert Kenneth Hefner. He knows nothing about his father. He thinks he may have died in northern California around Oroville in the late 1980's. He thinks he remarried and had children that could be my cousins. Any help with information would be welcome for me to start a genealogy for my father who is still alive and 76 yrs. old.
