Good morning, Thank you so much for this fabulous list, here is a little more info on the GAR & one that is not on the list SSMA. Yesterday, while volunteering at the DCHS in Broomall, PA, they asked me to identify a SSMA marker that has Marcus Hook (across the top), a number 12 (in the center), & SSMA (at the bottom) of the marker. SSMA stands for: S.S.M.A.--Soldiers & Sailors Memorial Association G.A.R.--Grand Army of the Republic: A society founded 1866 of Civil War veterans who served in the Union Forces. Happy hunting, Helen (DCGS)
