Lamont
A Scottish Highland clan name, probably meaning “son of Lamond,” with older roots that may ultimately be Norse or Gaelic.
The #5,114 most common surname in the United States (2010 Census) — about 1 in every 45,105 Americans shares it.
Etymology
The name is commonly explained as a clan surname from Gaelic Mac Lamont, meaning “son of Lamont” or “son of Lamond.” Older writers also connected Lamond/Lamont with a personal name that may be related to Old Norse or Gaelic forms, but the exact first element is uncertain. In some sources it is treated as a Scottish family name centered in Argyll, especially in the area of Lamont.
History
The Lamonts were an old Highland family of Argyll, and the surname is strongly associated with Clan Lamont. Historical references show the name in Scotland by the medieval period, and later spellings were often simplified from Mac Lamont to Lamont. The name also appears in Ireland, where it may reflect Scottish settlement or parallel surname development.
