I believe that my great-great-grandfather is the Daniel Marble that you refer to in your emails. He drowned in the Vermillion River in Ford County Illinois. I am a great-grandaughter of Malvina Marble Read, who was Daniel Marble's daughter. I am very much interested in obtaining a picture of him. Do you have one that could be emailed? If not, I could send my address and would be happy to reimburse you for the cost of making a copy.
