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 and Scottish: from Maurice, an Old French personal name introduced to Britain by the Normans, Latin Mauritius, a derivative of Maurus (see Moore). This was the name of several early Christian saints. In some cases it may be a nickname of the same derivation for someone with a swarthy complexion.
