History of the Fitzsimons name

Fitzsimons is an Anglo-Norman patronymic, fitz Simon, 'son of Simon', borne by families who came to Ireland in the thirteenth century. One branch settled in the Pale, in Dublin and Meath, where Fitzsimons were prominent merchants and civic officials of medieval Dublin; another established itself in Westmeath and Cavan, becoming so Gaelicised that some rendered the name Mac Síomóin. A separate settlement took root in County Down. The many spellings, Fitzsimons, Fitzsimmons and FitzSimon, are interchangeable. Dublin's most famous screen star, Maureen O'Hara, was born a FitzSimons of Ranelagh.
