Jan and Zofia Opaliński monument, church of Sieraków
Sofia Anna Czarnkowska (also called Zofia Czarnkowska Opalińska or Catherine-Sophie-Anne Czarnkowska) (12 March 1660 – 2 December 1701[1]) was a Polish noblewoman, known as the maternal grandmother of the queen of France, Marie Leszczyńska.
A monument was erected in 1748 in the church of Sieraków.[4] The crypt in a nearby castle contains the sarcophagus of the Opaliński family.
Among her matrilineal descendants is the King Juan Carlos I of Spain, who is her descendant through an unbroken line of Bourbon princesses from Marie Leszczyńska of France, who married within the Bourbon house.
