This thesis is a continuation of a previous research project examining the little-known phenomenon of foreign-born wives of Reformed ministers in the Transylvanian Reformed Church between the eighteenth and twentieth centuries. Building upon an earlier study that primarily focused on identifying and mapping the phenomenon and the individuals involved, the present work aims to provide an in-depth exploration of individual life stories and marriages. The research is based on archival sources, ecclesiastical records, parish registers, personal correspondence, family genealogies, and other original documents. Through a series of case studies, the thesis examines, among others, the marriages of Borosnyai Lukács Simon and Margarethe Hugh, as well as ifj. Eperjesi Zsigmond and Maria Wiskofski. The analysis demonstrates that foreign-born wives were required both to meet the expectations associated with the role of a minister's wife and to adapt to an unfamiliar cultural environment. The study contributes to a more nuanced understanding of the social and family history of Transylvanian Reformed ministers.
