The aim of this paper is to improve our understanding of the social intergenerational mobility in Geneva during the 19th century. We provide an indepth study of data collected from the marriage registrations acts. These documents provide us information on the spouses, but also on their parents and the witnesses. Our analysis focuses on the transitions between six social statuses defined from the professions found in the marriage Records. Since we collected all acts for married men with a name beginning with letter B, we have also in our dataset the act for the marriage of the father when he get himself also married in Geneva. This led us to split our population into those who have a father married in Geneva and those who have not. The first subpopulation corresponds to people that are established in Geneva since more than one generation, while the others are newcomers. We first show that these two subpopulations considerably differ both in their social structure and in their father-son mobility schemes. Then, focusing on the stable population, for which we have data available, we provide a mobility analysis through three generations using an original induction tree approach. Beside these strict social mobility aspects, we consider also a spatial dimension by looking at how the mobility is affected by the birthplace of the spouses. Finally, we examine the familial framework of the newlyweds, especially how the familial support and control differ between the newcomers and the more enrooted population. A detailed discussion of one large family of each of these two subpopulations enlightens their specific horizontal social mobility processes.
