There is a Rodman Coolidge buried in Malewood Cemetary, Henrietta New York.Died, 12/30/1893.Could this be the same person you are looking for. your died date is different. I was looking because my grandmother's name is Coolidge and she has a picture of a civil war soldier named Rodman Coolidge. Her family has roots in Henrietta NY. Her father's name was Fred and he may have been a step brother of Rodman.
