Tom, here is a link to the National Archives. All the information you need can be found there. I can help you with filling out the form. You can also use this same form to later request all his medals be reissued to you for free.
Do you know his full name? How old is he? I looked up Micheal Thompson in the local directory and there are 30+ listed. I have emailed the adjutant at our VFW which is only one of about 5 in the Hamilton/Northern Cincinnati area. I will see if I can contact American Legion in Hamilton, they don't have an email address that I can find so, I'll have to try to catch someone there and see if they will look on their membership roster.
Sorry I took so long, too many med. issues, lost track of time and didn't do much on the computer for follow up of web postings. As to you friend, no I don't know him, I don't belong to the American Legion in Hamilton and I am a transplant from Michigan so, don't know that many people here other than other transplants and fellow workers at GE, Cincinnati Milacron.
