I would like to find information on George Fosdick, who was a rural mail carrier in Preble County. He worked in the late 1890's or early 1900's. He was a mail carrier on the 1910 census. There is family lore that he was the first rural mail carrier in Preble County. I would like to know how to go about finding any information on this. Please let me know if you have access to any books or who to contact about the history of the postal service. Thanks for any help.
