Sheares brothers

The Sheares Brothers, Henry (1753–98), and John (1766–1798) were Irish lawyers and republicans who were members of the Society of United Irishmen, who died in the 1798 rebellion.
Early lives.
The Sheares brothers were the sons of Henry Sheares, a liberal banker from Cork who also sat in the Irish Parliament for the Borough of Clonakilty. Henry attended Trinity College Dublin, bought an officer's commission and then studied as a lawyer, being called to the bar as a barrister in Michaelmas term, 1790. John had qualified as a barrister in Michaelmas term, 1789. Their father had died in 1776, leaving a large income of £1,200 p.a.
Politicisation in Paris.
In 1792 the brothers went to Paris and were swept away by the popular enthusiasms of the French revolution. They met leaders such as Brissot and Roland, both of whom were to be executed in 1793. In particular they witnessed the introduction of the guillotine, on which 1,400 were to die in 1792. On the boat from France to England they met Daniel O'Connell (then a student) who was disgusted by the increasingly bloodthirsty nature of the revolution. O'Connell remained an advocate of non-violence thereafter.
United Irish.
They joined the United Irish movement on their return to Dublin in January 1793, when it was still legal. However, France declared war on Britain (and by extension, on Ireland) in February 1793. The Society's initial aims of securing 1) Catholic Emancipation and 2) universal suffrage were unsuccessful, amounting to the administration's 1793 Relief Act. Its stance became more radical, and in turn the Irish administration feared a group inspired by France, banning it in 1794. The Sheares brothers principally organised the movement in Cork, while continuing with their legal careers. A Mr. Conway, one of their keenest members in Cork, informed the administration of their activities. During 1793 the brothers also joined the Dublin Society of the United Irishmen, where another spy, Thomas Collins, passed on their names. Their two other less famous brothers had enlisted in the British army and were killed in action. On the arrest of most of the United Irish "Directory" members in March 1798, John was chosen as a replacement on the approach to the outbreak of rebellion. His main act at this point was to decide on the date - 23 May.
Arrests.
The Directory fatally stayed in Dublin, where the United Irish had less support. Already quietly betrayed by Conway and Collins, John also befriended Captain Warnesford Armstrong from County Down, who claimed to be a busy member of the party there. John never checked this, and Armstrong informed the authorities of the brothers' whereabouts, also appearing as a witness in the ensuing trial. They were arrested on 21 May and indicted on 26 June. (Christina, Lady Longford sets her 1942 play 'The United Brothers' in the drawing room of Lady Steele (Maria Verity widow of Sir Parker Steele Bt of Hampstead, Co Dublin) at 11 Merrion Square, Dublin, she had prevented John Sheares from marrying her daughter Maria Steele who later tried to save the brothers. 
Executions.
Inevitably the brothers were tried on 12 July, as the rebellion was at its height, and were hanged, drawn and quartered on 14th. The presiding judge was Hugh Carleton, 1st Viscount Carleton, the Chief Justice of the Irish Common Pleas, who was much criticised for taking the case, as the boys' father, a close friend, had appointed Carleton their guardian. Their lawyer was John Philpot Curran who, with Sir Jonah Barrington, obtained a stay of execution in the hope that Henry would recant, but the brothers were already dead. They were buried at St Michan's nearby. Visitors are brought to their coffins on a tour of St. Michan's vaults.
John's speech from the dock was later much quoted, including his justification:
Family.
All four Sheares brothers died in the 1790s, but Henry's daughter Mary went on to marry the Revd. Piers Butler in 1823. Their sister Jane Sheares married Henry Westropp and had issue.
