Fitzsimons Family History

Recorded in several forms as shown below, this is a surname of Anglo-Norman-Irish origins. Fitz denotes 'son of' and in the early medieval period was added to the personal name Sigmundr of Norse origin, meaning victory. The first records of this name in Ireland are after the Anglo-Norman Invasion of 1170. Amongst the families brought from England and Wales to County Down by John de Courcy in 1177 were some called Fitzsimon. Others of the same name followed the Prendergasts to County Mayo early in the next century. The most important line of this family came from Simonshide, given as being in Hertfordshire but probably Durham, and settled in Dublin in 1323...
