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.
