Giaglione (Val di Susa): comportamento matrimoniale tra ‘800 e ‘900

The present work is part of a project research on the people of Val Susa and Val Cenischia which includes studies related to aspects of biodemography, genetics , lifestyle and disease risk. The matrimonial behavior of the population of Giaglione (Susa Valley) between 1838 and 1939 has been analysed. The community under study is characterized, like many other alpine populations, by a marriage’s market with a high prevalence of endogamy for the first decades observed; exogamous marriages are largely confined to the towns of the main valley. After the 1915-18 war exogamy increased, both in terms of numbers and in terms of matrimonial distance, together with the number of marriages between persons born abroad, children of immigrants who returned to get married in their parents’s town/village of origin. Within endogamous marriages, the analysis of isonimy and of repeated pairs allowed to recognize internal divisions due to preferential marriages resulting from various factors - social, economic, political- and with an impact on the genetic structure of the population.
