I am seraching for more information on my grandmother's brother, Joseph Kelly. He was last found in the 1920 US census as a patient in the Fort MC Henry U.S. General Hospital No. 2, listed as an Army soldier. The family legend is that he lost an arm in the war. Irish civil records state that he was born in Malin, Donegal Ireland on May 1, 1889. He was the son of Patrick Kelly and Elizabeth Doherty.
I would like to find out where Joseph died and is buried. I have tried searching in several databases of cemeteries with soldiers.
