Around 1470, after the death of Świętosław, Jasienica was inherited by one of his sons - probably - Andrew, who having settled in this area took the name Klembowski (also Kłębowski) after - Klembów, the village which also became his property. After the incorporation of Mazovia into the Polish Crown in 1526, Jasienica was in the Mazovian Voivodeship, the Warszawa County and in the Warszawa Land.
