Dear All My maternal relative Governor William Calvin Oates was commissioned by the War Department between 1906 and 1909 to find and mark as many Confederate Sailors, Soldiers, and civilian graves through out the North. The government should have a record of this. I know that over 8900 graves were marked by him. IN one newspaper article published in 1909 he claimed that he identified in Chicago at least 10,000 graves. He also had monuments erected at Alton, and in Philadelphia and somewhere else in Pennsylvania also at Point Lookout. At Santa Fe. Also someone may want to contact the National Archives about records there.
