Surname meaning for Lamb
English: from Middle English lamb, a nickname for a meek and inoffensive person, or a metonymic occupational name for a keeper of lambs. See also Lamm. English: from a short form of the personal name Lambert. Irish: reduced Anglicized form of Gaelic Ó Luain (see Lane 3). MacLysaght comments: ‘The form Lamb(e), which results from a more than usually absurd pseudo-translation (uan ‘lamb’), is now much more numerous than O’Loan itself.’ Possibly also a translation of French agneau.
