My husband, Rich Clark, is Seymour's son and, of course, a grandson of Harry R and Sophia Smith Clark. We believe that this is a picture of Seymour due to the period look of the frame and clothing style. Thanks so much for posting it. We have been researching Rich's genealogy for almost four years now and have managed to trace back to the 16th century on most of his lines, including the Smith line. Have a lot of info on his grandmother Sophia but could only get back to Adrestus Clark, who is Harry's grandfather.
