Here is info from Find A Grave where I found the info on the other Hamner family members.
Birth: Mar. 26, 1904
Death: Aug. 31, 1990
The mother of writer Earl Hamner, Jr.
Doris Giannini Hamner was born on March 26, 1904, in the small village of Alberene in Albemarle County, VA. She was one of seven children. The family moved to Schuyler where she attended school in the wood frame building next to the Museum. At age 17 she married Earl Henry Hamner.
Her roots were of humble Italian immigrant stock. She was born in a remote crossroads town in Virginia. She never attended college, owned a company, worked out of the home or accumulated great wealth. Yet, Doris Giannini Hamner was personified by three outstanding actresses: Maureen O'Hara, Patricia Neal and Michael Learned and she became the basis for the most beloved mother in the hearts of America, Olivia Walton.
She passed away on August 31, 1990 after a long bout with Alzheimer's disease.
She is remembered as a loving mother and grandmother, a woman of deep and abiding faith, a fantastic cook who delighted in feeding family and friends, a hostess who welcomed Waltons fans to her home and the role model for Olivia Walton, the mother who has touched the hearts of the world for over a quarter of a century.
