Agnieszka Emercjanna Pociej née Warszycka

The likeness of Agnieszka Emercjanna Pociej née Warszycka (c. 1690 – after 1759), later married Joseph Alexandre de Montmorency de Bours, belongs to a group of 15 portraits which are traditionally believed to have been acquired by Stanisław August in 1764 from Kasper Lubomirski, together with the Ujazdów estate …
