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.
Princess Anastasia of Montenegro
Princess Anastasia Petrović-Njegoš of Montenegro (4 June 1868 in Cetinje, Montenegro – 25 November 1935 in Cap d'Antibes, France) was the daughter of King Nikola I Petrović-Njegoš of Montenegro (1841–1921) and his wife, Milena Vukotić (1847–1923). Through her second marriage, she became Grand Duchess Anastasia Nicholaievna Romanova of Russia. She and her sister "Militza" (Princess Milica), having married Russian royal brothers, were known colloquially as the "Montenegrin princesses" during the last days of Imperial Russia, and may have contributed to its downfall by the introduction of Grigori Rasputin to the Empress Alexandra.
