How does provincialism show up in the book To Kill a Mockingbird? (With reference to pride and ancestry.)

The term provincialism can be
defined in several different ways. It can mean narrow-minded, rude or narrow in outlook;
it can also refer to the characteristics of a particular region. In either case,
provincialism can be found throughout To Kill a
Mockingbird.

Aunt Alexandra may be the best
example of a provincial character in the novel. She fits both aspects of the definition.
She is overly proud of her family heritage (even though one of the Finches that she most
admired was apparently mentally unstable), and she believes that her family is a little
better than others in Maycomb County. She socializes only with the upper-class
townspeople, and views others (such as the Cunninghams) with
disdain.

To some degree, Boo Radley's parents also fit this
description. Overly religious and unsociable, they rarely mingled with their neighbors
and restricted young Boo to the confines of their home so he could no longer associate
with the type of people (the Cunninghams) who had led him
astray.
