Anglicized form of Gaelic Domhnall. The final -d of the Anglicized form derives partly from misinterpretation by English speakers of the Gaelic pronunciation, and partly from association with Germanic-origin names such as Ronald. This name is strongly associated with clan Macdonald, the clan of the medieval Lords of the Isles, but is now also widely used by families with no Scottish connections.
English: 1. habitational name, common in Lancashire and Yorkshire, from Buglawton or Church Lawton in Cheshire, or Lawton in Herefordshire, named in Old English as ‘settlement on or near a hill’, or ‘settlement by a burial mound’, from hlāw ‘hill’, ‘burial mound’ + tūn ‘enclosure’, ‘settlement’. 2. variant spelling of Laughton.
