 The modern name is derived from noble–bey (Omer-bey) family Šipraga.It is unclear whether their ancestors represent autochthonous population or they migrated into the area and acquired spacious property in the valley of the river Vrbanja and its tributaries.According to the oral traditions and cadastre records, their expansion started from Pougarje (slopes of Vlašić Mountain) in the valley of River Ugar.
