Some relatives remembered his first name as Karol; however, his marriage certificate with Agata and the death certificate of his son Antoni, mentions only Stanislaw.  Agata Pieniazek was his second wife; his first wife Marianna, maiden name Lis died probably in Gorzno.  Antoni, his son with his first wife married Rozalia Pieniazek, Agata's youngest sister.  When Agata's brother Jozef and and her father Adam Pieniazek left Slup near Parysow (also known as Pienki) for Swoboda near Siennica, the two Chmielak families purchased the Pieniazek's farm and house.
During the Second Word War the Polish Home Army (AK) partisans executed the Garwolin County Commissioner (starosta).  It is interesting to add that the commanding officer of the AK partisans was Stefan Zajac from Parysow, a schoolmate of Feliks Chajewski and Szczepan Pieniazek from the Podlasie Bishop's Gymnasium in Siedlce.  After the war, Stefan Zajac worked in the Polish National Bank.  One of his soldiers was Antoni Chmielak mentioned above (this could be Antoni's son, because Antoni died in Slup at the age of 62 in 1942).
As a reprisal for the execution of the Garwolin County Commissioner, Germans decided to "pacify" Slup on February 7, 1943*.  As the buildings in the village of Slup were spread out and surrounded by forest, most people got away, but not Stanislaw, who was shot by the Nazis in front of his house.  His wife Agata burned when Germans set fire to her house.
