The above information was obtained from the following:
(1) The State Summary of War Casualties from World War II for Navy, Marine Corps, and Coast Guard Personnel was compiled in April, 1946, by the Casualty Section, Office of Public Information, Navy Department. It is considered to be the official list of the World War II dead for the Navy, Marine Corps, and Coast Guard. These records can be found online at http://www.archives.gov/.

All of the names and information in this document are arranged by State. Within this document, the Navy states the following: "Inclusions of names in this State group have been determined solely by the residence of next of kin at the time of notification of the last wartime casualty status. This listing does not necessarily represent state of birth, legal residence, or official state credit according to service enlistment."

The casulaties listed in the document represent only those personnel on "active duty in the Navy, Marine Corps, and Coast Guard, resulting directly from enemy action or from operational activities against the enemy in war zones from December 7, 1941 to the end of the war." Any casualties in the United States area (training, other assignment to a permanent duty station in the US, etc.) or as a result of disease, homicide, or suicide, in any location, are not included..
