Abstract An exhaustive analysis of registers of births, deaths, and marriages is used to reconstitute genealogies, both ascending and descending, for all individuals who lived in two mountain valleys: the Valserine valley (in the French Jura), which is studied from the end of the seventeenth century to the present, and the Vallouise valley (in the French Alps) studied from the seventeenth to the nieteenth centuries. This genealogical approach makes it possible to trace the reproductive process in the populations whose members lived in the valley for several generations. The Vallouise valley forms an important demographic isolate; nearly 98 per cent of those born between 1820 and 1849 were descendants of ancestors who had lived in the valley two centuries earlier. By contrast, there has been continuous immigration into the Valserine valley, which has resulted in a constant renewal of the gene pool. Only 18 per cent of the gene pool of individuals living in this valley two centuries later was contributed by those who lived in the valley and who were born before 1750.
