Hi! Saw your message on the Genealogy.com message board re:WILLIAM ALISON ADKISSON, Lulu Henson, and your Grandmother.
Your Grandmother must have been either Willie L. or May E (Ruth) Atkisson. Her mother was Margaret (Maggie) L (Lulu) Henson Atkisson. Her Father is listed on their marriage record only as W.F. Adkisson. They were married on July 29th,1890 in Morgan County Tennessee. He was part of the Atkisson Family who were pioneers of Roane County, Tenn.
How do I know all of this? My Father, Robert Steven Dickey, was your Grandmother's stepbrother. Lulu remarried on August 13, 1899 to Stephen Gillis Dickey and had 6 more children: Della, Myrtle, Robert, Albert & Elbert (twins), and Roy.
I have been searching for information about your Grandmother's siblings/step...Anything that you can provide would be extremely exciting. Robert had a falling out with his family about 1928 and we have had no knowledge of or contact with since...I have been earnestly searching for my roots, but this is the first chance that I may gain some knowledge of my father's siblings and what happened to them and their families!
