The name "Rozka" likely has a surname character and derives from the word "rizka," which translates to "thin rod" or "willow." This name first appears in 1649 in the Registers of the Zaporizhian Army, specifically referring to a Cossack from the Braclav Regiment named Rozka Hordienko (RVZ 251). In Polish-origin documents from 1484, the anthroponym Roszga de Poltowsko is mentioned (SSNO IV 498).
