Question: I have determined that my grand uncle was serving with the U.S. Marine Corps in 1930 (per the U.S. Census). Can you tell me why I can not find his records online on commercial websites?
Answer: The records you see are not available online yet. It is not to say someday these will not be available online. Presently you need to request them from the National Personnel Center in St. Louis, Missouri. You can contact them online at: http://www.archives.gov/st-louis/military-personnel/
