Christine:

Should SKS of this board be unable to help on your quest suggest:

http://lists.rootsweb.ancestry.com/index/other/Military:_20t...
Military: 20th Century: GREATWAR Mailing List

Checking "Search the GREATWAR archives" re military medals and bars there are many references to your topic.

There is also WW1 messageboard but I find no Great War boards.
