Considered by many as the first "modern" war, World War One involved United States military units from 1917 to 1918. This database is a massive collection of military records for men who served in the war from Maryland. Originally compiled in 1933, it provides the names for men who served in the army, navy, and marines. In addition to providing the individual's name, it reveals city of residence, unit of service, birth date or age, and other helpful facts. It also contains the location and date of enlistment and discharge information. The names of over 67,900 men are included in the collection. For researchers of Maryland ancestors who may have served in the "Great War," this can be an informative database.
