John Sweetman (1752 – 1826) was an Irish republican, a delegate to the 1792 Catholic Convention and a member of the Leinster directory of the United Irishman.
[1] Sweetman was born of Catholic parents in Raheny, then a village north of Dublin, in 1752; the family had for more than a century operated an extensive brewery in the city.
He was a member of the Leinster directory of the revolutionary organisation, and some of the most important meetings of its executive committee took place at his brewery in Francis Street, Dublin.
After the suppression of the disordered insurrection in the summer of 1798, they entered into a compact with the government, by which, in consideration of a promise of the suspension of the executions of United Irishmen, they made full disclosure of their objects and plans, without implicating individuals, before committees of the Lords and Commons.
[1] Wolfe Tone wrote in his pocket-book on the day after he had been sentenced to death: Te nunc habet ista secundem ("This now has thee [Sweetman] as my successor").
