Gearóid O'Sullivan

Gearóid O'Sullivan (28 January 1891 – 25 March 1948) was an Irish teacher, Irish language scholar, army officer, barrister and Sinn Féin and Fine Gael politician.

Early life and education
Born the fourth son of Michael and Margaret O'Sullivan in Coolnagurrane near Skibbereen in County Cork, he was given the name of Jeremiah, but known throughout his lifetime as Gearóid. His father, a native of Lough Ine, and his mother, née McCarthy, a Coolnagurrane native, were members of prominent West Cork farming families.

Early into his education at the local national primary school, his intellectual capacity and promise of greater things was often remarked upon. Indeed, despite his young age, he was selected school monitor – a position of considerable responsibility, as the student monitors the progression of fellow students as well as the teaching capabilities of the teacher. He next studied at Daniel Duggan's Intermediate and University School in Skibbereen; at about this time, he was to meet several individuals who would draw him further into the Irish nationalist movement and deepen his appreciation of Irish language and culture. These included James Duggan, a local Sinn Féin activist and acquaintance of Gearóid's cousin Michael Collins. The two shared a grandmother on the McCarthy side of their respective families. Duggan encouraged Gearóid to join the Gaelic League, which he did at the mere age of 10. Notably, Gearóid's father, Michael O'Sullivan, chose to complete the family's 1911 Census form in Irish.

In 1909, O'Sullivan joined St Patrick's College of Education, in Drumcondra, Dublin, to train for a career in teaching. While not quite 19, he had already completed the second arts examination of the Royal University of Ireland. He took up teaching in 1911, but soon transferred back to Dublin to teach at St Peter's National School. He joined the Keating branch of the Gaelic League, quickly assuming a leadership role within the organisation and tirelessly travelling to teach Irish to League members while also studying for his BA at the National University and drilling with the Irish Volunteers. It was also here that he became re-acquainted with Michael Collins, who joined the League in 1916 upon his return to Ireland from London, where he'd held a Postal Service position.

Easter Rising
In addition to patrolling with the Irish Volunteers, O'Sullivan had the distinction shared by a small proportion of later "original IRA" members of being a member of the Irish Republican Brotherhood (IRB), which traces its roots to earlier revolutionary movements of the mid-Nineteenth Century. He also had the honour of raising the Irish Flag over the General Post Office (GPO) in Dublin as fighting raged around the Irish rebellion's GPO headquarters and throughout the streets of Dublin during the 1916 Easter Rising. O'Sullivan, then 25, was the youngest IRB officer fighting in the GPO. He had been personally chosen by rebellion leader Seán Mac Diarmada to serve as his aide-de-camp. The additional honour of raising the Rebel flag was given to him by another of the rebellion's leaders, Patrick Pearse.

Political career
Following the Rising, he was interned in Frongoch in Wales with Collins and others who, unlike the rebellion's leaders such as Pearse and Mac Diarmada, escaped execution. It was here that O'Sullivan's and Collins' friendship grew into a strong bond that would last until Collins' death in August 1922, with O'Sullivan – a Celt scholar – helping Collins polish his usage of the Irish language.

Upon release from Frongoch, Collins and O'Sullivan resumed their involvement with the Republican movement. During the War of Independence, at Collins' request, O'Sullivan agreed to replace him as Adjutant General of the Irish Republican Army. He was to become one of Collins' closest confidantes and run many secret missions for Collins, who often referred to him as "George," his undercover nom de plume. He would accompany Collins to many pivotal meetings, often risking his own capture; indeed, at one stage, there was a £3,500 bounty on his head.

At the 1921 general election, he was elected unopposed as a Sinn Féin Teachta Dála (TD) to the Second Dáil for the constituency of Carlow–Kilkenny. He was re-elected at the 1922 general election as a Pro-Treaty Sinn Féin TD. During the Irish Civil War he served as adjutant general of the National Army. He did not contest the 1923 general election.

After the war, he left military life to qualify as a barrister and build a successful career while spending time with his family with Maud Kiernan, which grew to include children Fr. Gearoid Jr., Sibeal, Ann and Sr. Trina. O'Sullivan had married Ms. Kiernan in November 1922; tragically it was to have been a double wedding of the Kiernan sisters Maud and Kitty Kiernan to O'Sullivan and Collins, respectively. Dressed in black for mourning, Kitty Kiernan cast a sorrowful figure at the wedding, occurring just two months after Collins' death.

In 1927, after the assassination of the then Minister for Justice Kevin O'Higgins, O'Sullivan, at the request of party leaders, contested the resulting by-election in the Dublin County on 25 August and retained the seat for Cumann na nGaedheal. He was re-elected in three subsequent general elections for the party in the same constituency. Then he unsuccessfully contested the 1937 general election for Fine Gael In 1938 he was re-elected to Seanad Éireann but was unsuccessful in the 1939 Seanad election. Following the death of his wife in 1940, when she was just 40 years of age, a grief-stricken O'Sullivan commenced a government service career, followed by a private legal career.

He died on Good Friday, 25 March 1948 and was given a State Funeral on the following Easter Monday – exactly 32 years after the Easter Rising. Thousands of people lined the streets of Dublin to watch as a horse-drawn carriage carried his coffin – draped in the same Tricolor that had covered Collins' coffin a quarter-century earlier – past the GPO and other landmarks to his final resting place at Glasnevin Cemetery. He died leaving a second wife, Mary Brennan of Belfast, and his four children.

In O'Sullivan's obituary appearing in the Irish Independent, an individual describing himself as "a colleague" wrote of O'Sullivan's contributions to Ireland following 1916:

"When the jails and prison camps opened Gearoid came back to resume the struggle. At a critical moment and at the instance of Michael Collins, he was summoned to an honourable, if highly dangerous, post – to replace Collins as Adjutant-General of the Volunteers. In the stern years that followed there was no braver heart or cooler head in the councils of the nation's army. From his dingy office, within a stone's throw of Dublin Castle, surrounded by excursions and alarms, meeting places where plans for action were settled, and thence to an uneasy rest."
