how did aunt alexandra classify any person from maycomb?

Aunt Alexandra is old-fashioned and proper, and often refers to the people of Maycomb in light of their family history. She seems to believe that behaviors and character traits are hereditary, passed on from one generation to the next - one family might have a Gambling Streak, or a Mean Streak, or a Funny Streak. She also judges families on the basis of how long they have been settled in the same place. Those who have stayed on the same land for many generations are deemed "Fine Folks," whereas Scout always thought that "Fine Folks" were those who "did the best they could with the sense they had."
