Gościński Ludwik "Przedpełk"
Ludwik Gościński („Ludomił Ziemicki”, „L. Ziemicki”, ”Polanin”, „Przedpełk”) was born on December 19, 1890, in Krościenko Niżne (a village later incorporated into Krosno, hence some biographies list Krosno as the birthplace), son of Józef, a tailor by trade.
After completing six years of primary school in Krosno, he attended a teacher's seminary and then enrolled in a Franciscan-run high school in Lviv, preparing for the priesthood, where he studied from 1906 to 1909. In 1909, he became a monk, taking the name Rajner.
Grabowski Robert "Radgast"
Unknown date and place of birth, as well as the names of his parents. He may have been associated with Zadruga before the war. This is suggested by Wacyk's information (see below – bibliography), who cites press notes about an alleged split in Zadruga and the departure of a "racist" group called "Radgast," led by Robert Grabowski. Although Wacyk explains that the information about the split was false (Zadruga members leaked it to the press to generate media interest), he does not deny the existence of Robert Grabowski himself.
Grzanka Józef "Warcisław"
Born March 10, 1912, in Ujma Wielka, Nieszawa County, son of Józef and Zofia née Więckowska. Graduated from the Mikołaj Kopernik Gymnasium in Toruń in 1933. Studied law at the University of Warsaw.
He completed the junior officers course at the 67th Infantry Regiment in 1934. Promoted to lieutenant in 1936, assigned to the 63rd Infantry Regiment.
He was called up for reserve exercises in 1935 and 1937 to the 63rd Infantry Regiment in Toruń. He received a very good opinion from his superiors after these exercises.
He practiced parachute jumping sportively, was a parachute instructor, and a glider pilot. He lived in Warsaw and worked part-time at the PAP service.
