Page "Morrison name evolutions are recorded in Edinburgh at this time. Those from the Clan Morrison may originally have been anglicised to Morison, with Morrison becoming more widely used later on.Another form of name changing came through rebranding of surnames. This occurred in Scotland for both convenience or necessity to disguise a Scottish Highland name, for example, McCoinnich describes the adoption of the name Morrison on the Isle of Lewis around 1640 by families formerly known as "McBrief" or "mac a’ Bhritheimh”. Alexander Morison makes the statement that the name is from ancestors who were vassals or adherents of the jarls of More or Moeri in Norway.Perhaps the earliest recording of the recognisable surname Morrison is found in the English Yorkshire Poll Tax records in 1379 for "Ricardus Morisson”. Some fifty years later in Scotland there is a Morrison recorded as "Arthuro Morison domino de Darleith" being a witness to the "Resignation by John MacRoger of Gleane MacKerne, in favour of John of Culquoune of Luss, of Gleane Mackecherne, etc. 7th February 1429". The spelling Morrison became more popular over Morisson and Morison later on.Following the gradual introduction of surnames in England, Scotland and Ireland many names such as Mirryson, Mirrison, Morisson, Morisone, Morrieson, Morriceson, Morason, Moorison, Mooresone, Morisoun, Moresoun, Murison, Muirison, Murieson, Murrison, Muresoun, Muirsoun and no doubt many other phonetic synonyms or Anglicised adaptations evolved and were standardised to become Morrison, Morison or Murison. Such standardisation in Scotland came after 1854 when Lord Elcho finally succeeded in framing An Act to Provide for the Better [Registration of Births, Deaths and Marriages" not found :(
