Does O'Connor's "Good Country People" reflect her own personal relationship with her mother Regina O'Connor?

Flannery O’Connor’s short story “Good Country People”
seems to reflect, in certain respects, O’Connor’s own relationship with her mother,
Regina.  In particular, the relationship between Joy/Hulga and her mother contains some
elements that seem relevant to O’Connor’s relationship to her own mother. Here are some
possible connections:

• Joy adopted a name
  (“Hulga”) deliberately different from her birth name.  O’Connor adopted a nom
  de plume (“Flannery”), somewhat different from the name (“Mary Flannery”) her
  parents gave her.


• Hulga has a wooden leg and is said at
  one point (in a splendidly bad pun) to “lumber” into the bathroom. O’Connor, as she grew
  older, became increasingly dependent on crutches. It’s possible that O’Connor, in giving
  Hulga a wooden leg, was mocking her own physical
  disability.


• O’Connor (unlike Hulga) had the ability to
  enjoy jokes at her own expense. Indeed, this personality trait made her quite endearing.
  In any case, Hulga is the handicapped daughter of a mother who runs a farm – exactly the
  same situation in which O’Connor and Regina found
  themselves.


• Mrs. Hopewell is a practical, efficient,
  commonsensical woman who has divorced her husband and who runs a farm with the help of
  hired hands. Regina O’Connor, of course, was a widow, but in every other respect she
  resembles Mrs. Hopewell.


• Regina O’Connor was intelligent
  and resourceful, but she was not the intellectual equal of her daughter (few people
  were).  Flannery O’Connor was widely read and deeply thoughtful, and there was often an
  element of tension in her relationship with her mother (whom she nevertheless loved and
  respected, and to whom she felt great gratitude). Flannery O’Connor was an
  “intellectual” in some of the same ways that Hulga is, although Hulga, with her extreme
  pride and extremely negative view of the world and other people, is in many ways the
  precise opposite of O’Connor.  Hulga is humorless; O’Connor had one of the best senses
  of humor in history. Hulga’s narcissism and nihilism make her significantly different
  from O’Connor. It was largely O’Connor’s sense of humor and her deep religious faith
  that allowed her to get along with her mother (and others) so well.
  


• Like Hulga, O’Connor was a well-educated young woman
  living at home, in her thirties, with her mother. A disability helped keep both young
  women living with their mothers, but O’Connor coped with her disability far better than
  Hulga does (to say the least).


• Hulga’s mother cannot
  quite comprehend her daughter’s decision to become a philosopher (a highly ironic
  decision, since Hulga is anything but a true “lover of knowledge” in the deepest sense
  of the term). Similarly, Regina O’Connor was a bit puzzled by Flannery’s decision to
  write stories and novels, and indeed O’Connor’s first novel, Wise
  Blood, caused a certain amount of embarrassment within the extended family.
  Eventually, of course, Regina took pride in Flannery’s accomplishments and in her
  increasingly distinguished career, but her own interests were far more practical and
  hard-headed than those of her daughter.  They had to
  be.


• In short, O’Connor presented, in the relationship
  between Hulga and Mrs. Hopewell, a comical version of her own relationship with Regina. 
  Hulga can be seen as O’Connor’s admonition to herself that she should never take herself
  too seriously – a temptation she was usually very successful at
  avoiding.
