Saya mau tau Gelar kerajaan dari Stanisław August Poniatowski

a  Sources vary with regards to whether Konstancja Grabowska and Kazimierz Grabowski were Poniatowski's children. They are listed as such by several sources, such as Jerzy Michalski's entry in the Polish Biographical Dictionary. However, a website dedicated to the genealogy of the Great Sejm participants, maintained by Marek Jerzy Minakowski, does not list neither Kazimierz nor Konstancja as children of Poniatowski. For Elżbieta, the genealogy lists only Kazimierz as a child of Jan Jerzy Grabowski.
