Irish names tend to vary widely in their spelling and overall form. The original Gaelic form of the name O'Shea is Ó Seaghdha, which is modified to Ó Se. The surname is derived from the word seaghdha which means hawk like but has a secondary meaning of stately. 1

Early Origins of the O'Shea family

The surname O'Shea was first found in County Kerry (Irish:Ciarraí) part of the former County Desmond (14th-17th centuries), located in Southwestern Ireland, in Munster province, where they held a family seat from ancient times.

The O'Shee variant claims Kilkenny as their ancestral home. At one time they were one of the most important of the ruling families of Kilkenny. Robert O'Shee was sovereign of the area in 1493. This family alternated using the "O'" prefix as not, as later his son Richard Shee, the Sovereign of Kilkenny (1545-1546) and (1553-1554) was Member of Parliament for Kilkenny in 1559.
