Etymology of the Surname Allen

  1. Celtic Origin: One of the primary origins of the surname Allen is Celtic, where it is derived from the Gaelic name “Ailín.” The name Ailín itself is a diminutive form of the Gaelic word “ail,” meaning “rock.” This origin is particularly associated with Scotland and Ireland, where the name Allen was adopted by families as an anglicized form of their Gaelic names.
  2. Norman Origin: Another source of the surname Allen comes from the Old French name “Alain,” introduced to England by the Normans following the Norman Conquest of 1066. The name Alain was popular in medieval France and likely derived from the name of a Celtic tribe, the Alans, who were present in the Roman Empire.
  3. Anglo-Saxon Origin: In some cases, the surname Allen may also be derived from the Old English personal name “Ælfwine” or “Ealdwine,” meaning “elf friend” or “old friend,” respectively. Over time, these names evolved into the shorter form “Allen.”
