This article is an attempt at a reconstruction of the most important family connections of the Krupa family inhabiting Kamionka and a suburbian village Siedliska on the basis of preserved court registers. The marriages they entered into with the Rusek family (otherwise related to the Lublin patriciate) seem to be of key importance for their social status. This bond was established on two paths. Firstly, by Dorota Krupa – married to Jan Rusek – and by Maciej Krupa, connected by marriage with Regina, the daughter of Anna Benedyktowa de domo Rusek. The Krupa case served as a starting point for considering factors which have influence on forming of marriages. This consideration concerns in particular the rule of “economic equality of marrying people”. Research results prove that apart from the economic element other, extra-economic factors such as the position of the family in a local society or self-reliance, etc., played a crucial role as well.
