First, thank you for what you are doing to honor and remember our fallen heroes. As the daughter, granddaughter, wife, niece, sister, and aunt of U.S. Veterans, your dedication to these men's memories, moves me deeply.
This is a link to a certificate for John Daniel Pratt:http://www.wwiimemorial.com/registry/wardept/pframe.asp?Hono...
At that site, you can search by name, perhaps you'll find something on your other four veterans.
I will see what else I can find on Mr. Pratt and will be in touch with you. Do you have a specific date that he died in 1944? I would like to search the microfilm of the Lewiston Tribune to see what they carried about his death/service.
