Dear Mr. Lockard,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located Logbooks of U.S. Navy Ships, ca. 1801-1940 in the Records of the Bureau of Naval Personnel (Record Group 24) that includes the Log of U.S.S. ST. LOUIS: 4/13/1889-10/21/1889; and the Logbooks of the USS Yorktown
for April 23, 1889 - December 8, 1897. Some of these logs have been digitized and may be viewed online using the National Archives Catalog. We also located the Muster Rolls of Naval Ships, 1/1/1860-6/9/1900 in Record Group 24 that may contain the muster rolls of the USS St. Louis and USS Yorktown for 1889. Some of the records have been digitized and are available using the Catalog. For more information about the non-digitized logs, please contact the National Archives at Washington, DC - Textual Reference (RDT1) via email at firstname.lastname@example.org.
Next, we located the series Weekly Returns of Enlistments at Naval Rendezvous, 1/6/1855-8/8/1891 in Record Group 24 that contains 55 files related to League Island, including 2 files for 1889 that may be relevant to your research. These records have been digitized and may be viewed online via the Catalog.
If you have not done so already, we also suggest that you request a copy of John Laverty’s Official Military Personnel File (OMPF). OMPFs and medical records of enlisted men of the U.S. Navy who were separated from the service after 1885 and before 1959 are located at NARA's National Personnel Records Center (NPRC), (Military Personnel Records), 1 Archives Drive, St. Louis, MO 63138-1002. To request these records, please mail a completed GSA Standard Form 180 to NPRC. Veterans and their next of kin also may use eVetRecs to request records. See eVetRecs Help for instructions. For more information see Official Military Personnel Files (OMPF), Archival Records Requests.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RDT1. Also, NPRC will continue servicing requests ONLY associated with medical treatments, burials, homeless veterans seeking admittance to a homeless shelter, and those involving the VA Home Loan program. If your request is urgent, please see Emergency Requests and Deadlines. Please refrain from submitting non-emergency requests such as replacement medals, administrative corrections, or records research until NPRC returns to pre-COVID staffing levels. Please check archives.gov/veterans for updates to the NPRC operating hours and status. We apologize for this inconvenience and appreciate your understanding and patience.
We hope this is helpful. Best of luck with your family research!
