 The name was introduced into the country through Margaret (died 1093), the Hungarian-born wife of Malcolm III, King of Scots; in time one of their sons became Alexander I, King of Scots (died 1124).One of the earliest instances of a form of "MacAlasdair" are records of "Ranald Makalestyr", who obtained a lease of lands in Arran, in 1455.Ranald is later also referred to in documents as "Ranald Alexandri", and "Reginald McAlestir" (also "McAlestere" and "McAlestre").
