I know from past mails that some listers have German ancestors.  In case you don't know the International Red Cross have recently made the index cards of Prisoners of the First World War available (military and civilian). I've found my husband's grandfather and great-uncle here... they were both interned at Knockaloe on IOM. http://grandeguerre.icrc.org/   ......be prepared to brush off your rusty French or German (that is, if your language skills are as unused as mine) The site includes all POWs and internees, so of interest to more than just descendants of  interned Germans!
