I noticed that there is a July 1863 photograph of the home of a G. J. White near Gettsyburg online. An old man appears at the gate and a woman in a hoop skirt is on a porch. Any idea whose White family this is? It is accessible via the Prints and Photographs Library of Congress website, digital file LC-DIG-cwpb-03853. You can pop LC-DIG- cwpb-03853 into Google and the photo will be item 5 on the list. Cheers, Laura in NC
