The Military Order of the Purple Heart is an organization of men who have been awarded the decoration. It's a private organization so you can only reasonably expect them to have information on him if he is, or has been, a member or if he's had some sort of contact with them at one time or another. They won't, of course, give you his life story but should be willing to provide his full name, service number, date of birth, unit and a few other items considered to be public information. They have a website at < http://www.purpleheart.org/http://www.purpleheart.org/ > (click on the address to go there). Go to the 'site. When you arrive, scroll down until you come to a menu of links.
