Generally the Murison name is not a commonly know scottish family name and at times is often confused with Morrison, but the name Murison is relatively an old family name know in the north east of Scotland and surrounding areas of Aberdeenshire. Murison is patronymic in origin 'son of Muris' and possibly a variation of the french Maurice which could be either from a personal name introduced to Scotland by the Normans after the invasion of 1066 or the later Templar settling in the Aberdeen area. There is also a possible link going back even further to the Norwegian Viking settling in the north and north west of Scotland who had extensive trade links to the Picts in the North East.

The given name Maurice is derived from the latin Mauritious, indicating a moor, which may possibly be evidence of the templar connection. In heraldry the Murison Crest includes the heads of three moors, or black African in profile. The use of the “Moor’s Head” as a heraldic device dating from the 13th century and the emblem has connections to the Crusades reflecting associating families with victories over the moors.

Variants of this surname include:  Murieson, Murrison, Muryson, Murysone, Mwyrson, Murisons, Murson, Murescun, Muresoun, Muirsoun, Muirison

In about the year 1187, William the Lion granted part of the Culter lands on the south bank of the river dee in Aberdeenshire to the Knights Templar and between 1221 and 1236 Walter Bisset of Aboyne founded a preceptory for the Knights Templar so there is a possible link with the Murison name and the Templars that settled in the north east of Scotland.

It has also been claimed that in 1309 during the trial and persecution of the Templars Bishop Lamberton of St Andrews who was Guardian of Scotland from 1299 - 1301 gave the Templars his protection, though there is no evidence to support this as all Templar records disappeared during their persecution in europe.

The earliest record is in 1448, in Scotland when one Simon Mwyrson was recorded as a husbandsman of the Grange of Abirbothy.

In the same year, one Johannes Murysone is listed as a burgess of Kircaldy and Sir William Mureson, a cleric, was admitted burgess of Aberdeen in 1491. Cybke Murisone was a tenant of part of Kethik in 1504 and in 1528 Archibald Murson was a bailie for Arbroath Abbey in Banff. Records show that John Murescun was a follower of Campbell of Lundy in 1529 and William Muresoun was reidare (a reader or one in minor orders in the Scottish church after the reformation) at Crouden in the 1574. George Muirsoun of Ferne was a follower Walter Ross of Morange in 1596.
