Veterans buried in or from Australia

I am looking for any information on American Civil War veterans buried in or from Australia/New Zealand for the Veterans Memorial Website, www.acwv.info.

If you know of, or have an ancestor who participated in the American Civil War I would like to acquire information on them. If thay have no grave marler; I can acquire one free of charge. Descendants can also receive a "Presidential Certificate" honouring their service, signed by the President of the United States. jamesmgray@bigpond.com
