I have no knowlge of whom settle Longtown, but I am aware of a post of the underground railroad, in nearby Fountian City,Indiana by the name of Levi Coffin House. Also the undergound railroad also opperated not far away in Wilberforce, Ohio not far from Xenia, Ohio. Some members of my family on my mother side were brought to Randoplf County Indiana via Quakers. Some mixed with people from Longtown, also Richmond, and Portland, Indiana.
