Discovering your veteran’s story in Navy records
We’ve all heard about the 1973 Fire at the National Personnel Records Center in St. Louis, Missouri and the impact on the Official Military Personnel Files (OMPFs) for Army and Army Air Force veterans. No one really talks about the OMPFs for the Navy, Coast Guard, Marines, and Merchant Marines. Those still exist and are available to request.
What many people do not realize is that while you wait for the OMPF to arrive for your Navy veteran, there are many options online to start piecing together your Navy veteran’s story. Naval Muster Rolls are one place to begin.
You can find Naval Muster Rolls on Ancestry: U.S., World War II Navy Muster Rolls, 1938-1949.
Fold3: U.S., Navy Muster Rolls 1938-1949 and US, Navy Muster Rolls, 1949-1971
You can also find the rolls on NARA’s Catalog but they are much easier to use on Ancestry and Fold3.

Why Do I Need Muster Rolls?
Muster Rolls document all changes to Naval personnel as they move through their World War II service. The Muster Rolls are created for Changes as seen on the image below and also as Rosters of those on board a ship (at sea) or in a station (on land). There are a good way to gather some puzzle pieces about where someone served, when he or she was being sent for training, and other details.
Important! Naval Muster Rolls also contain the names of Army, Army Air Force, and Marines who are being transported aboard Naval vessels. Just because your veteran didn’t serve in the Navy doesn’t necessarily mean he or she isn’t listed on a Muster Roll.
A Naval Muster Roll is going to provide you with the following information:
- Date of the report the roster or change.
- Type of Report (Change or Roster)
- Name of individual. Service Number. Rating. Date of Enlistment. Place of Enlistment. Each of these entries is numbered.
- Use that number to look at the bottom of the page to see what changes were made.

The bottom of a Muster Roll provides the following information:
- Branch of Service within the Navy. For instance this can mean for a V-6 that your veteran enlisted in the Voluntary Reserve under the Naval Reserve Act of 1938.
- Received (col 7) means were they received aboard the station/vessel or transferred, etc.? What was the change being made?
- Date of occurrence means the date it happened or the effective date. So if the Report of Changes covers more than one day, the exact date your veteran had a change is shown there.
- Vessel or station (col 9). This tells you where someone is coming from or going to.

What Does it all Mean?
The Muster Roll will provide you with the footsteps or paper trail of the ships and stations on which your veteran served. Or in the case of other branches, perhaps the ship on which he was transported. The rolls provide the puzzle pieces, sometimes incomplete, but you can take this information and put it into a Timeline of Military Service to better understand where your veteran was during his or her service.
Important! When you research Navy service, there is a whole other language you have to learn to decipher what is contained not only on Muster Rolls but also in War Diaries, Deck Logs, OMPFs, IDPFs, and other Naval related documents.

You can also search for ‘Navy abbreviations and acronyms’ or the exact abbreviation you need defined.
What if I Can’t Trace My Veteran?
Sometimes it is challenging to trace a veteran through the rolls. There are several reasons for this which include the following.
- The records no longer exist or the search function can’t find your veteran due to damage to the document or issue when it was digitized.
- Your veteran was placed on a ship and remained there most of his service. He had no changes so nothing was reported on the rolls.
- Your veteran may have been part of the Naval Armed Guard which was placed aboard Merchant Marine vessels. The crews of those vessels are not listed on Naval Muster Rolls. You will need to get the OMPF to learn which vessels a veteran served on and obtain Merchant Marine Armed Guard Reports and Deck Logs to learn more about that part of his service.
The Naval Muster Rolls are a great resource and one that is easily accessible when you begin your military research. They should be at the top of your list to explore. Finally, since we never know if a website or record set will disappear, I encourage you to download every Muster Roll you find so you can always refer back to the information it holds.
