Dear Joan,
I am not a relation of Hamilton Littlefield. However, my friend and I have been trying to do research on him and his family. He was an abolitionist in Oswego and a well known businessman. We have been trying to put the pieces of his life together. It would be wonderful to locate descendents to see if they have additional materials. Are you a relation and do you have information which would assist us? We would be glad to exchange information.
