House of Rostworowski

The Rostworowski (plural: Rostworowscy, feminine form: Rostworowska) is a Polish aristocratic family, originating in Greater Poland and using the Nałęcz coat-of-arms. Their name comes from the village of Rostworowo near Poznań, that was the family's original seat.

Since the 18th century, descendants of the castellan of Zakroczym Jan Antoni Rostworowski (1709-1775) and his wife Konstancja Lanckorońska (1721-1777) claimed a hereditary title of a count. Although it was not ever formally conferred on any member of this family, due to their high social standing and family connections, the Rostworowskis used to be addressed as counts both by their noble peers and European monarchs.

The family is noted among Polish aristocracy for a number of prominent intellectuals (often associated with the Roman Catholic Church) such as:

Kraków

Gębice, Greater Poland

Żyrzyn, Lublin region

Rybna, Lesser Poland
