The paper introduces the life of an ordinary villein Martin Jaroš who lived in the village of Kročehlavy. The description of his life story is based on a land register (started in 1607), which shows the potential of this kind of source to bear evidence of people’s lives. The land register does not provide any information about the childhood of Martin Jaroš, but it describes his adult life in detail. It discloses the fact that he acquired his surname Jaroš together with a homestead which he bought in 1584. Before that, his name was probably Němec. This homestead was the largest in the village, which might have been the reason why he did not manage to pay it off. In the year 1618 he left it to his son Jiří and took possession of an inn. He kept it until 1626 when he retired. He died probably between the years 1628-1629. In addition, we know about his four sons and his brother Václav. The author tries to show how valuable the information from a land register can be for the reconstruction of the life story of an ordinary villein.
