Thank you for posting your request on History Hub.
Here is a site which might be useful for you, as it gives information on how to locate current duty US Marine Corps personnel.
I hope this is helpful in your research!
Hello Ms. Carpio,
Another possible route would be to request the Official Military Personnel File (OMPF).
OMPFs for active U.S. Marine Corps personnel or selected Marine Corps Reserves are in the custody of the U.S. Marine Corps. To request these records, please mail a completed GSA Standard Form 180 to Headquarters, U.S. Marine Corps, Manpower Management Support Branch (MMRP-10), 2008 Elliot Road, Quantico, VA 22134-5030.
Privacy laws may restrict who can request the OMPF but it could be another avenue of inquiry.
