Legend has it that for five great Gaelic families — the O ' Gradys, the O ' Neills, the Ó Briains, the Ó Conchobhairs, and the Caomhánachs — the lament would be sung by a fairy woman ; having foresight, she would sing the lament when a family member died, even if the person had died far away and news of their death had not yet come, so that the wailing of the banshee was the first warning the household had of the death.

The family surname mac Aedh Ó Proinntigh was Anglicised as Prunty or Brunty.

Ó hÓgáin proposes that this term was also used in Scottish Gaelic and Welsh.

According to a report in the Cork Examiner, the Continuity IRA's first chief of staff was Dáithí Ó Conaill, who also served as the first chairman of RSF from 1986 to 1987.

According to Ruairí Ó Brádaigh, it was Seán Mac Stiofáin, as chief of staff of the IRA, who invented the name.

However, under his usage, the name was written and pronounced according to Irish orthography and pronunciation as " P. Ó Néill ".

The 1975 IRA-British truce is often viewed as the event that began the challenge to the original Provisional Sinn Féin leadership, which was said to be Southern-based and dominated by southerners like Ó Brádaigh and Ó Conaill.

One of the reasons that the Provisional IRA and provisional Sinn Féin were founded, in December 1969 and January 1970, respectively, was that people like Ó Brádaigh, O ' Connell and McKee opposed participation in constitutional politics.

It was in 1983 that Ruairí Ó Brádaigh resigned as President of Sinn Féin and was succeeded by Gerry Adams.

Grace O ' Malley ( c. 1530 – c. 1603 ; also Gráinne O ' Malley, ) was Queen of Umaill, chieftain of the Ó Máille clan and a pirate in 16th century Ireland.

Eoghan Dubhdara Ó Máille was Gráinne's father, and his family was based in Clew Bay, County Mayo.

He was chieftain of the Ó Máille clan and a direct descendant of its eponym, Maille mac Conall.

Ní Mháille was married in 1546 to Dónal an Chogaidh Ó Flaithbheartaigh ( Donal of the Battle ), tánaiste or heir to the Ó Flaithbheartaigh ( O ' Flaherty ) title, which would have been a good political match for the daughter of the O ' Mháille chieftain.

As an arranger and composer his credits include, The Seville Suite which was inspired by the exploits of Aodh Rua Ó Dónaill from The Battle of Kinsale in 1601 until his arrival in Galicia to the welcome of The Spanish Earl of Caraçena.

" O " was originally Ó which in turn came from Ua, which means " grandson ", or " descendant " ( of a named person ).

It was founded just over 750 years ago by King Felim O ' Connor ( Irish: Fedlimid Ó Conchobair )

His funeral was attended by Ruairí Ó Brádaigh, the then president of Sinn Féin, Michael O ' Riordan of the Communist Party of Ireland, Bernadette McAliskey and local Wicklow TDs Liam Kavanagh ( Labour ), Ciarán Murphy ( Fianna Fáil ) and Godfrey Timmins ( Fine Gael ).

The entire idea was thwarted by the Ireland's Minister for Community, Rural and Gaeltacht Affairs, Éamon Ó Cuív TD, saying that the Gaeltacht could not legally be split into zones.

Later Irish immigrants have continued to contribute to Bermuda's makeup, with names like Crockwell ( Ó Creachmhaoil ) and O ' Connor ( Ó Conchobhair ) now being thought of locally as Bermudian names.

The government parties, Fine Gael and the Labour Party, could have nominated a joint candidate, but following the debacle over the events that led to the resignation of President Ó Dálaigh, it was thought unwise to do so.

There was a large Ó Catháin castle in Limavady thought to be the chief residence of the clann, which has fallen into ruin, and it is situated in the Roe Valley Country Park just outside Limavady town.

It is thought that Ó Rathaille was born in Screathan an Mhil ( Scrahanaveal ), in the Sliabh Luachra region of County Kerry into a relatively prosperous family.

It is thought that the Ó Cionnaith sept was part of the Uí Maine kingdom, based in Connaught.

In fact Dubhaltach's only remark thought to be connected with this time is what Ó Muraíle calles a " breathtaking understatement " that Dubhaltach writes in the Díonbhrollach ( preface ):

At about this time he changed his name from John Reidy to Seán Ó Riada, after giving the subject much thought.

He is believed to have been in this position since the death of Dáithí Ó Conaill, the first chief of staff, in 1991.

Vacancies in the presidency have occurred three times: on the death of Erskine Hamilton Childers in 1974, and on the resignations of Cearbhall Ó Dálaigh in 1976 and Mary Robinson in 1997.

In this poem Seán Ó Seanacháin likens the grip that drink ( An Buachaill Caol Dubh-the dark slender lad-probably a whiskey bottle ) has on him to the love that a young man would have for him.

In March 2005, Minister for Community, Rural and Gaeltacht Affairs Éamon Ó Cuív announced that the government of Ireland would begin listing only the Irish language versions of place names in the Gaeltachtaí as the official names, stripping the official Ordnance Survey of their English equivalents, to bring them up to date with roadsigns in the Gaeltacht, which have been in Irish only since 1970.

Ó Dálaigh's actions were seen by government ministers to have contributed to the killing of this Garda.

Lyons, John A. Murphy, Roy Foster, and James S. Donnelly, Jr, as well as historians Cecil Woodham-Smith, Peter Gray, Ruth Dudley Edwards and Cormac Ó Gráda have denied claims of a deliberate policy of genocide.

Modern Irish clan organisations such as Clan Ó Lorcáin ( Larkin ) have elected honorary chieftains, where no Chief of the Name is known or yet to be proven.

There have been two Chief Executives of TG4, Cathal Goan ( former Director-General of RTÉ from 1996 to 2000 ) and the current Director General, Pól Ó Gallchóir.

Ó Sándair is reputed to have published 160 books and sold more than 500, 000 copies.

Ruaidri Dáll Ó Catháin, an Irish harpist of the 17th century most famous as the composer of Tabhair dom do lámh, may have penned the popular Irish tune the " Derry Air ", in order to lament the destruction of Ó Catháin power.

Consequently, it may have been originally called " Ó Catháin's Lament ".

They have produced some musical gems, now standards, like " Les filles des Forges ", " Les prisons de Nantes ", " La Jument de Michao ", " Pelot d ' Hennebont ", and new interpretation of Irish music, like " Cad é sin don té sin ", " Si mort a mors " ( originally An Cailín Rua ), " La ville que j ' ai tant aimée " ( from " The town I loved so well "), " Mrs McDermott " ( from the 17th-century Irish harpist Ó Carolan ) and " Kalonkadour " ( from " Planxty Irwin ").

Two of O ' Hanlon's children have served as local politicians in Cavan – Monaghan, a son Shane is a former member of Monaghan County Council and a daughter Fiona O ' Hea served one term on Cootehill Town Council while the Sinn Féin TD Caoimhghín Ó Caoláin, is also a relation of O ' Hanlon.

Pádraig Ó Snodaigh, author of the book Hidden Ulster, Protestants and the Irish language, states that many of the settlers came from Gaelic speaking areas in Scotland and thus would have culturally meshed well with their new neighbours.

The same year, the State Department revoked his multiple entry visa and have since refused to allow Ó Brádaigh to enter the country.

On 10 February 1975, the IRA Army Council, which may have included Ó Brádaigh, unanimously endorsed an open-ended cessation of IRA " hostilities against Crown forces ", which became known as the 1975 truce.

Ó Caoláin is married to Briege McGinn and they have four daughters and one son.

Aodhagán Ó Rathaille was related to the brehons to the Mac Cárthaigh Mór family and would have seen them as his chiefs and patrons ).
