MACBETH Family History
This is an anglicized form of the Old Gaelic personal name MacBeatha translating as 'the son of (mac) life (beatha)' or 'a man of religion'. The most famous namebearer was Macbeth (1005 - 1057) who became King of Scotland in 1040 after he slew Duncan. Known as Macbeth, the Usurper, his reign was ended by Malcolm III, Canmore, who defeated him in 1057. The personal name is also recorded in Ireland as early as 1014. The 'Annals of the Four Masters' tell of one, Macbeatha who took part in the Battle of Clontarf.
