The Historical Marker Database can be a very useful tool when researching your military ancestors. Historical markers can be found throughout New York State listing those who served in various conflicts including: the Revolutionary War, War of 1812, Civil War, Spanish-American War, World War I, World War II and the Korean War.
Of course, as with anything other documentation, the markers may not be 100% accurate so if your ancestor is not listed on a marker it does not mean they did not serve in that conflict. Always be sure to do your research to verify the information found on the marker.
