Have you guys read the book Ghost Towns by Barbara Solem Stull? On page 119 of the book it that Chetwood attempted to start a brick works at martha but it never took off. Sometime between 1860 and 1863 Chetwood sold most of the Martha tact to Amory Edwards. Chetwood had planned to biuld a railroad through the area. Surveyors found the route impractical. They built the railroad through Chatsworth and Atsion instead. I don't know if this helped. I hope it did.
