In "Good Country People," how are the characters' names significant? Is there any symbolism?

In her creation of Manley Pointer, author Flannery
O'Connor has given birth to one of literature's greatest names. He lives up to both of
them: Although pretending to be an innocent, country bumpkin, the highly
confident Manley shows his manly side when he seduces Hulga. Like the hunting dog for
which he is named, Manley sniffs out his prospective victims, and then flushes out their
insecurities before taking advantage of them. The name also conjures up phallic
connotations. 

Joy/Hulga Hopewell is another great
combination. As Joy Hopewell, she showed great promise as a youngster, but after losing
her leg, she becomes embittered with life and all around her, and she chooses one of the
ugliest possible names to fittingly reinvent herself.

Mrs.
Freeman's name is ironic, of course, since she is a tenant farmer relying on the support
of the Hopewells. Mrs. Freeman's daughters, both teenagers with plenty of sexual
experience, apparently are quite willing to give themselves freely to any man. Mrs.
Hopewell consistently lives up to her name, always hoping that all will turn out well
for her and her daughter.
