Nemo me impune lacessit was the Latin motto of a dynasty known in Gaelic as what ?
House of Stuart The House of Stuart, originally Stewart and, in Gaelic, Stiùbhart , was a European royal house that originated in Scotland. The dynasty's patrilineal Breton ancestors had held the office of High Steward of Scotland since the 12th century, after arriving by way of Norman England. The royal Stewart line was founded by Robert II, and they were Kings and Queens of Scots from the late 14th century until the union with England in 1707. Mary, Queen of Scots, was brought up in France, where she adopted the French spelling of the name, "Stuart". Her son, James VI of Scotland, inherited the thrones of England and Ireland upon the death of Elizabeth I in 1603. Except for the period of the Commonwealth, 1649–1660, the Stuarts were monarchs of the British Isles and its growing empire, until the death of Queen Anne in 1714.
Butler dynasty The House Butler refers to the several branches of the Butler family (Irish: "de Buitléir" ) that has its origins in the Hiberno-Norman or Cambro-Norman family that participated in the Norman invasion of Ireland in the 12th century. Variant spellings include "le Boteler" and "le Botiller". The surname has its origins in the hereditary office of Butler of Ireland. The family originates with Theobald Walter, 1st Chief Butler of Ireland. Many of the branches eventually begin to extend out to various countries in Europe and North America as many descendants immigrated out of Ireland and England in later years.
