 The Kojović and Djaić in Čičevo near Trebinje also descend from the Sokolović in Foča, and have the slava of Mratindan.Petar Rađenović's anthropological work "Bjelajsko Polje i Bravsko" (1925) mentioned a Sokolović family in the Muslim village of Bjelaj, Bosanski Petrovac, as one of three Serb families, which had in 1921 settled from Ripač; they have the slava of "Đurđevdan", and hail from Čajniče, and were earlier surnamed Glođajić.In the period of 1920–31, Serb and other South Slavic families of the Kingdom of Hungary (and Serbian-Hungarian Baranya-Baja Republic) were given the option to leave Hungary for the Kingdom of Yugoslavia, and thereby change citizenship (these were called "optanti").
