What does the O'Shea name mean?

From Ó Séaghdha, descendant of Séaghdha ('hawk-like' or 'stately'). The Ó Séaghdha were the principal sept of Iveragh, the great peninsula of south Kerry running from Killorglin to Cahersiveen and Valentia Island. Their stronghold was at Ballycarbery Castle on the Cahersiveen coast, in continuous Ó Séaghdha possession from the 13th century to the Cromwellian confiscation. The Anglicised O'Shea remained densely Kerry-rooted into the modern era, with secondary concentration in west Cork.

The history of O'Shea

The Iveragh Ó Séaghdha were one of the Munster septs, holding their lordship under the MacCarthy Mór kings of Desmond from the 13th century to the Tudor era. The chiefly seat at Ballycarbery, the smaller fortress at Castlecove, and the family lands across the modern peninsula passed through formal surrender-and-regrant under Henry VIII (1543) but were lost in the Cromwellian settlement. The Ó Séaghdha remained densely planted across Iveragh through every subsequent census; the modern Kerry-O'Shea diaspora is heaviest in the New York and Boston Catholic Irish communities.

Katharine 'Kitty' O'Shea (1846–1921) was the long-term partner and (after 1891) wife of Charles Stewart Parnell, the leader of the Irish Parliamentary Party; their relationship became public during her husband Captain William O'Shea's 1889 divorce petition, and the resulting scandal split the Irish nationalist movement and effectively ended Parnell's political career. Milo O'Shea (1926–2013), the Dublin-born actor, played opposite Vanessa Redgrave in Ulysses (1967) and the Pope in The Verdict (1982); his face is one of the visual signatures of mid-20th-century Irish-Hollywood character acting. Tessa O'Shea (1913–1995), the Cardiff-born singer and entertainer, was 'Two-Ton Tessa' of the British music halls.

Stories of O'Shea

Kitty O'Shea and the Parnell divorce
1890
On the fifteenth and seventeenth of November 1890, in the Probate Divorce and Admiralty Division of the High Court of Justice at the Royal Courts of Justice on the Strand in central London, the divorce petition of Captain William O'Shea (Irish Parliamentary Party MP for Galway 1880–86) against his wife Katharine Kitty O'Shea (1846–1921, born Katharine Wood, daughter of an English-Sussex baronet) was heard before Mr Justice Sir Charles Butt. The co-respondent named in the petition was Charles Stewart Parnell, then forty-four years old, the leader of the Irish Parliamentary Party at Westminster, the effective political-architect of the Irish-Home-Rule programme and (since the 1885 election) the political-balance-of-power figure in the House of Commons between Liberals and Conservatives. The divorce-case revealed publicly the eleven-year relationship between Parnell and Kitty O'Shea, three children born to the couple, and the tacit acceptance by Captain O'Shea of the relationship in exchange for political favours from Parnell. The political-consequence of the public disclosure was, by every careful judgment of the Home-Rule historians (F. S. L. Lyons, R. F. Foster, Roy Jenkins), the political destruction of Parnell within seven weeks. The Irish Parliamentary Party split between the Parnellite minority and the anti-Parnellite majority at the Committee Room Fifteen meeting of the sixth of December 1890. Parnell married Kitty O'Shea at Steyning Registry Office on the twenty-fifth of June 1891 and died of pneumonia at their Brighton home on the sixth of October 1891, forty-five years old. The Irish Home Rule political-movement was, on the Parnell collapse, leaderless for the next twenty years.
