Romani victims of Nazi persecution and German expellees developed as distinct memory communities after 1945, but the pre-war integration of Sinti and gadje in East Prussia has left traces in their memory texts. Non-Romani texts and photos contain rare evidence for aspects of Sinti life before the genocide, much of it now available (only) on the internet. Conversely, Sinti were among the Germans who were forced to leave East Prussia after 1944, and awareness of dual trauma and nostalgia for the Heimat they shared with other Germans is apparent in their memory texts. The article explores these points of contact between the two memory communities and their implications for more solidary forms of remembering and re-visioning the region's multiethnic past.
