Origin uncertain. Possibilities include: 1. Reduced and altered form, under French influence, of Polish Rzepiński (see Repinski). 2. altered spelling of German Reppin, a habitational name from a place named Reppin (of Slavic origin) in eastern Germany. 3. altered spelling, under French influence, of Russian Repin or Slovenian Repina, both from nicknames based on the Slavic word repa ‘turnip’.
