The story of family life in wartime is the most powerful vector of transnational history. This chapter examines how families faced the tide of war. The shape of family history may be glimpsed in a general way through standard demographic indicators. Demographic change is glacial in character: it reflects earlier patterns and moves very slowly over time. There is some evidence that the elderly suffered increased mortality during the war. This was in part because the mobilisation of farm labourers meant that elderly men had to pick up the plough again, and to manage farms at times without farm animals. The chapter deals with the return home, the centripetal forces bringing families back together, separating others, and creating new forms of kinship among victims of war. It also considers the enduring aftermath of the war, in the sense of its lingering legacy on family life.
