Petar II Petrović-Njegoš
Petar II Petrović-Njegoš was born Radivoje "Rade" Petrović on in the mountain village of Njeguši, near Cetinje. His father, Tomislav "Tomo" Petrović (b. 1762–63), was a member of the Petrović clan of the Njeguši tribe of Katuni "nahiya". Njegoš's mother, Ivana Proroković, hailed from the hamlet of Mali Zalaz and was the daughter of Njeguši captain Lazo Proroković. There is no reliable information about her exact year of birth, but it is believed that she was about ten years younger than her husband. Tomo and Ivana had five children; their eldest son was Petar ("Pero"), Rade was their middle son and Jovan ("Joko") was their youngest. The couple's daughters were named Marija and Stana; Marija was married to a Montenegrin chieftain named Andrija Perović, the "serdar" (count) of Cuce, while Stana was married to Filip Đurašković, the "serdar" of Rijeka Crnojevića.
Stanojlo Petrović
Petrović purchased a house in Belgrade. Stanojlo and Draginja Petrović became prominent figures in Belgrade society and friends of many authors, artists, tradesmen, scientists and politicians. The "Draginja and Stanojlo Petrović Endowment" supported more than 17 different charitable organizations. Petrović and his wife Draginja were among the first public benefactors in Belgrade, giving university scholarships to needy students attending the "Grandes écoles"'s Faculty of Orthodox Theology which would later become the University of Belgrade.
