Show ContentsFitzsimons History, Family Crest & Coats of Arms

Despite the fact that the Irish already had developed a system of hereditary surnames, the Anglo-Norman invaders imported their own naming principles. The Strongbow invasion marked the first introduction of non-Gaelic elements into Ireland. One of the most common types of surnames at this time was the patronymic surname, which was formed from the name of the initial bearer's father. Often, and especially in the case of French names, this was done through the addition of a diminutive suffix to the given name, such as "-ot," "-et," "-un," "-in," or "-el." Occasionally, two suffixes were combined to form a double diminutive, as in the combinations of "-el-in," "-el-ot," "-in-ot," and "-et-in." Another way of forming patronymic names used by the Strongbownians was the use of the prefix "Fitz-," which was derived from the French word "fils," and ultimately from the Latin "filius," both of which mean "son." Although this prefix probably originated in Flanders or Normandy, it is now unknown in France and is found only in Ireland. The surname Fitzsimons is derived from the personal name Simon. The common Norman form of this name was Simund, which was ultimately derived from the personal name "Shim'on," which is derived from the verb "sham'a," which means to "hearken." The name features the distinctive Irish patronymic prefix "Fitz," which means "son of" in Anglo-French. The Gaelic form of the surname Fitzsimons is Mac Shiomóin. Variations in the spelling of this surname were extremely common.

Early Origins of the Fitzsimons family

The surname Fitzsimons was first found in County Cavan, where they had been granted lands by the Earl of Pembroke for their assistance in the Anglo/Norman invasion in 1172. Though Fitzsimmons is an ancient name in Ireland, the surname is actually derived from the Normans and made its way into Ireland by way of England.

"This family came from England to Leinster in 1323. Earlier than that it was in Mayo. " [1]
