The article addresses the question whether, besides major historical events like that of the Second World War, experiences of gradual change are also transmitted from one generation to the next within the family, and, if this is the case, whether these familial memories are an instance in the formation of collective representations. By analysing narrative interviews with “three-generation families” the authors compare families representing two social milieus that have undergone profound change during the last few decades, namely agriculture and steel industry. The comparative analysis starts from the hypothesis–eventually to be refuted–that sociostructural factors or, more precisely, heritage and heritage relations influence memory processes in farmer’s families to a much higher degree than in working class families, thus hampering the integration or “co-production” of familial memories and the collective memory of social change.
