New York state's World War I dead
The United States entered World War I late, in 1917, but the epic conflict exacted a heavy toll on American troops and on Long Islanders. The war left 347 troops dead from 108 communities in Nassau and Suffolk counties, according to the New York State Military Museum.
The museum compiled its information from the "Roll of Honor" of the state's war dead issued by the New York National Guard's Adjutant General's Office in 1922. Some of the information on the fallen troops is not conclusive - so only those people who were definitively from New York have been included in Newsday's database.
