Malbrough Family History
Malbrough Surname Meaning
English: habitational name from Malborough (Devon) or Marlborough (Wiltshire). The Wiltshire placename 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 Anglicized form of Gaelic Ó Maoilbhearaigh (see Mulberry).
Perhaps also an Americanized form of German Malburg.
