I am researching the men of the 81st Pa., and compiling their burial locations. I have a Thomas Mulhall, or Mullhall who served in Co. H, 81st Pa. during the Civil War. His wife, Margaret applied for a widow's pension from Iowa in 1902. I am thinking he must have died there in 1902, or shortly before then. Any help in locating his burial site would be much appreciated.
