assist for honoring a veteran

i’m a pastor in Ohio and became just asked to do the provider for a ninety year ancient veteran of the air drive who handed on Christmas Eve. What little family he has knows nothing about his carrier and that i don’t have any means of figuring out or finding out the place he served or in what means, but i need to honor him smartly. Can any one give me any information? ways i will be able to find out about his service?
