Unknown Man

This photo was found with our Shaeffer family photos. I think it may be H W Shaeffer/Schaeffer. The spelling has changed over time. H W probably stands for Henry William. If this is him he was born about 1845 in Pennsylvania and lived in Moniteau Co., Missouri where he married Malinda Anna Nickles, daughter of Peter Nickles Jr and Mariah Gross-Nickles. No one in my family knows what happened to him after 1894. It is speculation he had another family as he was a traveling salesman or he may have perished in the Johnstown Flood. Does anyone have any ideas who this man is??
