Charles,
sorry, the whole site at www.volksbund.de seems to be in German with the exception of a couple of pdf files.
You may try the way via www.yahoo.com and give the URL www.volksbund.de/graebersuche in the search field. What you get is a search result mentioning exactly this site. Just click on "Translate this page" and you'll get a translated version of that page at least. You may proceed by clicking the button titled "zur Onlinesuche". Sorry, there is no complete translation available at this time.
Regards,
Joe
