O'Callaghan

Most Irish patronymics point back to a man who cannot be dated. This one does not. Ó Ceallacháin means descendant of Ceallachán, and the Ceallachán in question is Ceallachán mac Buadacháin of the Eóganacht line that ruled Cashel, king of Munster from 935 until his death around 954. Cashel was the spiritual capital of the province, and the sept that later handed the name to English as Callaghan began as the principal family of the Eóganacht Cashel.

What the personal name meant is less settled than who carried it. Cellach is read as 'bright-headed' in one account of the surname and as 'strife' or as 'small church' in another, and the three readings pull in three directions: a description, a temperament, a place of worship. The root is contested; the man is not. Everything the surname later did in Cork, in Clare, in Spain and in America runs back to a tenth-century king whose name nobody can now translate with confidence.

The Munster sept were lords of Cinéal Aodha, a country in Cork lying west of Mallow along the valley of the Blackwater. Their earliest ground was north Cork around Mallow itself, and the Anglo-Norman expansion of the twelfth and thirteenth centuries pushed them west off it. They did not scatter: they settled permanently in mid-Cork and stayed there, which is why the surname is a Cork name today rather than a name spread thinly across the province.

The country they held took their name in English, as Pobble O'Callaghan, and the chiefly seat stood at Drominagh, the modern Dromaneen. The lordship survived as a near-independent one into the sixteenth century, well after the Norman settlement had rearranged the ground around it, and the line held the seat continuously until the confiscations of the seventeenth century took it away.

Don Donough O'Callaghan submitted to Henry VIII in 1543 under surrender and regrant, giving up a title held by Irish custom and taking his own country back from the crown on English terms.

The seat at Drominagh stayed in the line and the country kept its name. What ended the lordship was not the Tudors at all. It was the century that followed them.

The family came out of the Irish rebellion of 1641 on the losing side, and Donough O'Callaghan's land near Mallow was forfeited. The Cromwellian Plantation then dispossessed the sept of its ancestral home and of 9,700 hectares, some 24,000 acres, and moved the family into East Clare. Losing a seat is one thing; being physically transplanted off the Blackwater valley altogether is another, and it is the hinge of the whole surname's history.

East Clare still carries the name on its map, at O'Callaghans Mills. The Cork land went to a family called Longfield, or Longueville, who put a twenty-bedroom Georgian mansion on it. The ancestral estate of the O'Callaghans thus became somebody else's country house, with the old name attached to nothing but the district.

The Williamite forfeiture of 1691 finished what 1641 had started and broke the lordship for good. Many O'Callaghans left with the Wild Geese and served in the French and Spanish armies through the eighteenth century, which is how a Blackwater valley surname became a continental one. Spain carries it still: José O'Callaghan Martínez (1922-2001) was a Spanish Jesuit, papyrologist and Biblical scholar.

Others of the name made careers inside the British establishment. Robert O'Callaghan (1777-1840) served as a British Army officer and sat as a politician; George O'Callaghan, 2nd Viscount Lismore (1815-1898), was an Irish peer and a British Army officer in his turn.

A reader named Callaghan from Armagh, Louth, Meath or Monaghan may well not be a Cork O'Callaghan at all. An entirely separate sept, Ó Ceileacháin in Irish, belongs to those counties. The Annals of the Four Masters record its members as lords of Uí Breasail, a district on the southern shore of Lough Neagh, and as priors of Armagh in the eleventh century.

English took that name apart differently in every county it met. It appears as Kelaghan, Keelaghan and Kealahan; in County Meath, where it is widespread and concentrated in the parishes of Kells, Trim and Athboy, it was largely written as Callaghan, Callahan or O'Callaghan and so became indistinguishable on paper from the Munster name. In Westmeath it settled as Kellaghan and Kelleghan, and in Monaghan it is often simply Keelan. Fivemiletown in County Tyrone was once Liscallaghan. Two unrelated families, one modern spelling, and no way to tell them apart except by where the family came from.

Very few Irish families dispossessed in the seventeenth century ever saw the ground again. This one did. In the twentieth century some 202 hectares, about 500 acres, of the ancient O'Callaghan land returned to O'Callaghan hands when Longueville House was bought by a descendant of the Donough O'Callaghan who had forfeited it.

The house is now a hotel, owned by William O'Callaghan. It is a small fraction of the 24,000 acres taken under Cromwell, and it is no restored lordship. It is something rarer: a Gaelic surname standing again on named ground the Cromwellian plantation moved it off.

Pat O'Callaghan (1906-1991) was the first Irish athlete to win an Olympic medal, which is a place in a nation's sporting record that can only be occupied once. His brother Con O'Callaghan (1908-1976) was Ireland's first Olympic decathlete. Two national firsts inside one family.

Bill O'Callaghan (1868-1946) was an Irish hurler; Donncha O'Callaghan, born 1979, played international rugby union for Ireland; Miriam O'Callaghan served as the twenty-sixth president of the Camogie Association. Mollie O'Callaghan won Olympic swimming gold for Australia.

Two Medal of Honor recipients carry the surname, spelled two ways. John O'Callaghan (1850-1899) received it as an American soldier. Joseph T. O'Callahan (1905-1964), a Jesuit priest who served as a captain in the United States Navy, received it with the g gone from his name.

The name also went north. Edmund Bailey O'Callaghan (1797-1880) was a doctor and journalist who led political movements in both Ireland and Quebec. Leland James O'Callaghan (1915-1997) was an American businessman and politician in Georgia. The Munster patronymic Ó Ceallacháin, moved off a river valley by force under Cromwell, ended on Olympic rolls, on American citations for valour, and back on the ancestral estate.
