Hi, I have volumes of information on the Parker clan, and, unfortunately, I have found no one who knows of any painting of Nathaniel Parker or any of his children. I descend of Nathaniel Parker Sr's. youngest son, Robert. I do have a photograph of Robert Parker Sr.'s granddaughter, Martha Parker Perry. I, too, would be interested in photographs of any of the descendants of Nathaniel. Sincerely, Sherry
