Peruz Terzekyan...Dates do fit. Could she be the "Little Peruz", a singer of cantos and a love interest of Petri.
1876 He fell in love with the bordello owner Kaloferiya's 12-13 year old daughter Peruz. He gave a valuable jewel from Lefteri Kaptan's belt to her mother, took the young girl to his Dolapdere shack and raped. Later he had her picture taken at a potrait studio. (unknown location, possibly a Pera Studio. The photo was lost.)
1880 Upon hearing rumors of a new singer named Peruz in Galata casinos, Petri with fishermen buddies from Kalikratya decided to check if she was his Little Peruz. indeed she was. Petri killed a sailor named Ahmet when he found the unlucky suitor in an amourous embrace with Peruz at the bar of Avrupa Tiyatrosu in Galata. Peruz escaped. So did Petri. Possibly police found a pair of slippers at the crime scene.
Peruz Terzekyan (b. Sivas 1866?- d. .....Istanbul) , the Kanto Singer
Started singing cantos in 1880 ies when she was almost 14. She composed her songs and was also the lyricist. Her stage life lasted until 1912. Her songs were published as "Nese-i dil ". Peruz was a pioneer with Şamiram, Baydzar, Büyük Amelya, Küçük Eleni, Virjin Avantiya, Mari Ferha and Agavni all non-muslim (mostly Armenian) canto singers.
Peruz was also credited as a lead in 1919 silent short " Fahri Bey Makarna Tenceresinde/Mr. Fahri in Pasta Pot" by Ismet Fahri Gulunc. Rusen Hakki and Gulunc himself were other actors. Gulunc directed another short film of the same year "Tombul Asigin Dört Sevgilisi/Four Darlings of Plump Lover" . The film was not completed de to a legel dispute and there were no credit records for Peruz. However we know that Peruz was really a plump woman at her youth and could be the women in this film also.
