‘The most important principle of all our inheritance and family law is the preservation of the patrimony.’

—Josep Faus i Condomines, 1907

Marriage strategies leading to the biological and social reproduction of the family were the main goal of stem family households in Catalonia. This goal was closely linked to the maintenance or increase of the family inheritance, mostly in terms of arable land. The ‘house’, which in Catalonia connotes the family household, lay at the centre of this system. The aim of this article is to analyse some Catalan marriage strategies, together with inheritance and social customs. This will be carried out through an analysis of the matrimonial behaviour of a stem family living in the village of Sant Pere de Riudebitlles over 300 years, from the seventeenth to the nineteenth century. We will show how this family achieved its main biological and social reproduction goals. Our inquiries use the techniques of L. Ferrer-Alòs and A. Fauve-Chamoux. As D. S. Reher has remarked, ‘The only way to flesh this out adequately is to look at the system from inside out, in terms of the way individual families sorted out their destinies within the context they had inherited…it would also be most interesting to be able to observe succession strategies of families according to their concrete demographic constraints such as number, age, and gender distribution of their offspring surviving past early childhood.’

P. Laslett – first in 1972 and later in 1983 – coined a typology for the analysis of the household. He defined a household as a domestic coresident group, wherein people with or without family ties live together, sharing the main meals. The Laslett household classification scheme has been widely used by researchers. However, Laslett's scheme has had some critics, who object to its static approach to family and household analysis. Our view is that domestic coresident group analysis should be dynamic; that is to say, we should study the household by observing its different stages, and considering the social, economic and historical framework of its geographical area. This framework helps us to determine the logic of family behaviour and the various strategies which a family might pursue in order to achieve a particular goal. We believe that these aims do not stand in contradiction to the Laslett typology.
