Mielżyński

As magnates and members of the szlachta, they built dynastic connections to the royal houses of Europe through marriage.

Anna Miełżyńska (1600-1640) was the grandmother of Catherine Opalinska, the queen consort of King Stanislaus Leszczynski of Poland.

The connection through Anna Miełżyńska was extensive for the Mielżyńskis, linking a Polish family to the blood lineages of the House of Bourbon; thereby the thrones of France and modern Spain.

His sons, Stanisław Kostka and Mikołaj, appeared in the 1824 list of persons authorized to bear the title of Count in the Kingdom of Poland.

Josef (1765–1824; son of Maceij by his wife Seweryna Lipska) obtained the hereditary title of Count from King Frederick William III of Prussia on 12 July 1817 (L.P. 20 January 1818).
