Hi Clyde, welcome aboard. I'm familiar with that area and can offer a couple of suggestions. First, I see that there are several census records on Family Search for Ignatius Drury in Franklin County PA, along with a Civil War Soldiers Index record. There's a Find A Grave entry for Ignatius "Nathan" Drury (d. 1903) in State Line, PA. They're free sites, and you may get several leads from there. If you are in the vicinity, the Kittochtinny Historical Society in Chambersburg has a lot of old records from the area. Also, I think the local libraries in Chambersburg, Greencastle, and Waynesboro all have genealogy rooms with a lot of material, and there is a historical society in Waynesboro as well. But I would try web searching first. Good luck.
