Register of Commissioned and Warrant Officers of the United States Navy and Marine Corps, January 1 1956
If your ancestor served as an officer in the U.S. Navy or Marine Corps during the mid-19th or early 20th century, you may find his or her name in the U.S. Navy and Marine Registers collection. An officer's "given name" often includes both a first name and a middle name or middle initial. If only a middle initial (rather than the full middle name) is known, omit the initial and enter just a first name in the search box.
In addition to searching the U.S. Navy and Marine Registers, you may also browse each individual volume in collection by clicking first on the title, then on the "Browse this database" link located under the search box. The introductory pages of these digitized books often contain information about pay rates, career fields, and other valuable details about your ancestor's military service.
