Both Letters in "The Paris Review"

The two letters in the Paris Review book are extremely different.  I thought they might have some kind of relationship because of the titles, but was very mistaken.  The "Letters to Williamsburg" is a little vulgar, but I feel her piece is all about the setting and she incorporates herself into the entire piece as a way of finding herself.  In "Letters to Kentucky" you kind of get the same feeling.  The voice of the letter is talking all about his home and his father, maybe I'm not grasping the deeper meaning to both of them, but I need some kind of outside ideas or clarification.
