The name 'Bratchyna' has its roots in Ukrainian records from the 16th century. For example, in 1565, Bratchyna Kunatovsky is mentioned (ArchYUZR VII/1 195) and Kunas Bratchyna - a peasant from Bar (Arch YUZR VII/2271). This name is derived from the word 'Bratko' by using the diminutive suffix '-yna', similar to names such as Hrytsyna, Ivanina, Senyna, Fedyna, as well as words like kozachina, khlopchyna.
