Family name origins & meanings
- English : habitational name from Malborough (Devon) or Marlborough (Wiltshire). The Wiltshire place name is from an unattested Old English personal name Mǣrla or Old English meargealla ‘gentian’ + beorg ‘hill’, ‘mound’.
- Irish : possibly a variant of the County Clare surname Malborough, Marlborough, which MacLysaght considers to be probably an Anglicization of Gaelic Ó Maoilbhearaigh (see Mulberry 2).
- Perhaps also an Americanized form of German Malburg.
