Inmigración europea y modelos familiares: la legitimidad de los nacimientos y la sexualidad fuera del matrimonio en la población francesa de Tandil (Buenos Aires), 1850-1914

This article, based on a family reconstitution of French people in Tandil between 1850 and 1914,shows the advantages and disadvantages of this method and the sources; illegitimacy and its associated factors (parents’ age, endo and exogamy, rural/urban differentiation, etc.). and the incidence of pre-marital children and conceptions. The indicators obtained were analyzed and compared with other Argentinean and French socio-demographic contexts. In the conclusion I propose that illegitimacy among the French population in Tandil is a consequence of a different family conformation pattern from that of the native population.
