I am the grandson of David S. Coffin who is the son of James Berton Coffin and Nancy Argo. James Berton coffin is the son of Peleg R. Coffin and Roxy Wright. I also am trying to trace Peleg Coffin. The 1850 Illinois census for Piatt, Illinois shows Peleg's birthplace as New York. I am currently researching the New York Census records, which is time consuming. I also plan to try and obtain a copy of Peleg's death certificate in the hope that it will list his mother and father. My research indicates that Peleg died on Sep 15, 1870. in Sangamon, Piatt, Illinois and is buried in Mackey Cemetary, Piatt,Illinois. If this is the same Peleg, as I discover more information about Peleg I can keep you informed and if you have information please feel free to keep me informed.
