Know Your Records: U.S. Navy Muster Rolls/Personnel Diaries

U.S. Navy muster rolls and personnel diaries (online ID 594996) are among the most popular U.S. Navy records in our holdings, along with U.S. Navy deck logs. Archivists at the National Archives in College Park, MD (Archives II) frequently consult these records to answer researcher requests. We discussed deck logs in a previous post. Today let’s take a look at U.S. Navy Muster Rolls and Personnel Diaries!

U.S. Navy Muster Rolls/Personnel Diaries – What they are:

Information found on muster rolls and in the personnel diaries may be helpful in identifying the ship, station or activity to which an officer or enlisted man was attached, as well as significant status changes that may have occurred during their service.

Muster Rolls are lists of naval personnel formerly attached to a ship, station or other activity. These reports are generated quarterly. Information usually available on muster rolls includes:

  • Name of enlistee
  • Rating (occupation/specialty)
  • Service number
  • Date reported for particular duty or on board
  • Date of enlistment
  • Name of ship, station, or activity
  • Ship number or other numeric designation
  • Date of muster roll

Personnel diaries are the U.S. Navy equivalent of the morning rosters found in U.S. Army records. These personnel diaries were compiled monthly. They record significant status changes, including reporting to or transferring from the activity; being promoted or demoted; departing for or returning from periods of leave, and temporary attached duty. Information usually available on personnel diaries includes:

  • Name of enlistee
  • Date of the change
  • Explanation of the change

Nuances of Muster Rolls

  • For the period of 1939-1956, muster rolls list the names of enlisted personnel only. Some of the rolls do include the original place of enlistment.
  • For rosters of officers serving aboard commissioned U.S. Navy ships during the period 1939-1956, researchers must consult the deck logs of the ship; however, the National Archives does not have custody of officer rosters of Navy units and shore establishments.
  • From March 1957 onwards, the muster rolls include lists of officers AND lists of enlisted personnel.

Muster rolls/Personnel Diaries from 1971 onward utilize social security numbers as service numbers and therefore are subject to privacy restrictions (see below).

What they are not:

Muster rolls do not provide daily lists of naval personnel formerly attached to a ship, station, or other activity. They will not tell you the daily whereabouts of a sailor during their service.

Muster rolls/personnel diaries do not contain current addresses of former naval personnel or their survivors.
