OShea

O'Shea is a surname of Irish origin, derived from the Gaelic Ó Súilleabháin, meaning "descendant of Súilleabháin." The name Súilleabháin itself is believed to be derived from the word "súilleabhán," meaning "little dark-eyed one." It is a common surname throughout Ireland, particularly in the Munster province.

Historically, the O'Shea clan was prominent in County Cork and County Kerry. They were associated with the Eóganachta dynasty, a powerful Gaelic royal family that ruled Munster for centuries. Like many Irish surnames, O'Shea has spread globally due to Irish emigration, particularly to countries like the United States, the United Kingdom, Canada, and Australia. Notable individuals with the O'Shea surname come from various fields, including politics, sports, arts, and entertainment. The spelling variations of the name can include O'Shea, Shea, and Sheahan, among others. The ancestral seat of the O'Shea family is often cited as being in the region of Muskerry in County Cork.
