Hi Lisa, I haven't been on these message boards for years. But I saw this post and wanted you to know what a treasure the post cards are. I hope to create a scrapbook with them one day. One of the cards was actually written by my grandfather to his mom. We believe that Nellie Sheridan actually lived at the National Hotel as her sons are shown on census records with their grandparents. We've searched high and low but can't find her. Thanks again for your thoughtfulness!
