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: habitational name from any of several places called Dockray, of which there are four examples in Cumbria. A possible origin of the place name is Old Norse dǫkk ‘hollow’, ‘valley’ + vrá ‘isolated place’; the first element is, however, more likely to be Old English docce ‘dock’ (the plant).
