Archibald m. Old High German erchan 'sublime, special; chief; ge nuine, true' + Old High German bald 'bold'.
The Old German form of the name is Erchambold, but the m was retained only in French and Italian. In Scotland, Archibald was a common name amongst the earls and dukes of Douglas, Moray, Argyll, and Angus, and was often used as a translation of the Gaelic name Giolla Easpuig.
