Clans Seen in Macbeth

Clan MacBean: Donaldbain, Duncan, Malcolm, Macbeth
 
  The Gaelic 'Ban' or Bain means ‘fair’ and with Scottish
              blood made up with so much Norse and Germanic stock this descriptive term could
              have been applied to many people.  Indeed the name is found associated with
              several clans in many districts.  There was an early Scottish King called
              Donald Ban, who was the son of Duncan and Malcolm's brother.

Clan MacDuff: MacDuff, Lady MacDuff, Gruach

Clan Duff originated from the Royal Scoto-Pictish line, of which Queen
              Gruach stood as its senior representative. Her son, Lulach, succeeded the throne but
              was murdered in 1058, whereby Malcolm Canmore won the throne.

Stewart: Banquo, Fleance, Lennox, Menteith

The Stewart family records its traditional descent from Banquo, Thane of
              Lochaber.  Historically, however, the family appears to be descended from an
              ancient family who were seneschals of Dol in Brittany.  They acquired
              lands in England after the Norman conquest and moved to Scotland
              when David I ascended to the throne of Scotland.  This line eventually sits on both the
              thrones of England and Scotland in the person of King James I and VI.

Ross: Ross

The name Ross derives from the ancient Celtic word “Ros”, meaning “a
              promontory”, in this case the lands of Easter Ross.

Mac Innes:  Angus

MacInnes is a Celtic name derived from Mac Aonghais - Gaelic for the
              son of Angus.
