Dear Ms. Foster,
Thank you for posting your request on History Hub!
We suggest beginning your inquiry with the National Personnel Records Center (NPRC) - St. Louis. They can determine precisely what Military Honors he is entitled to. Please submit a completed SF-180 to 1 Archives Dr. St. Louis, MO 63138-1002. Include any documents regarding his service you have, such as the DD-256 to assist with locating holdings pertaining to his service.
We hope this information is useful and best of luck with your endeavors!
