We use to go visit Grandaddy Livingston. I remember walking to his sister's house through the woods. His daughter Frances lived next door to him. He also had a sister that lived down the highway a little ways and across the street. His son Truman Livingston that was lost in WWII is my grandfather. My mother use to go spend the summers at his house when she was a young girl.
My mom remembers the store burning. She also remember that he was a teacher at the 2 places you listed.
