Lappin Family History

Irish: from Ó Lapáin ‘descendant of Lapán’ perhaps a nickname from lapán ‘little fist’. Sometimes Anglicized as Delap or Delapp in Ireland.

English: from the Middle English personal name Lapin possibly a nickname for a timid person from Old French lapin ‘rabbit’ or it may be a derivative of Old English læppa ‘lap (of a garment)’ ‘sleeve’ ‘small strip of cloth or hide’ ‘person's lap or bosom’ ‘flap of flesh’ ‘piece of land at the edge of an estate’ but what sense the derived term might have when used as a surname is unclear.

Polish and Jewish (eastern Ashkenazic): variant of Lapin.
