Grierson

Clan Grierson is a lowland Scottish clan.

The surname Grierson is a patronymic form of the medieval Scottish personal name Grier which is a form of the personal name Gregory. It has been speculated by some that they may descend from the same line as Clan Gregor, however this is refuted by others. Gilbrid MacGregor was given a charter of the lands of Dalgarnock in Dumfriesshire, by the Earls of March. The principal seat of the Griersons was Lag, which was obtained in about 1408.

Until his death on March 24, 2008, the chief of Clan Grierson was (Sir) Michael John Bewes Grierson of Lag, 12th Baronet. The chief had represented the clan at the Standing Council of Scottish Chiefs. The crest badge of clan member of Clan Grierson contains the Latin motto: HOC SECURIOR.
