John Henry Colclough (/ˈkoʊkliː/, COKE-lee;[1] c. 1769 – 28 June 1798) was a United Irishman, who was executed in Wexford following the Irish Rebellion of 1798.
He was born circa 1769 into an old landowning Wexford family, the son of Thomas Francis Colclough and lived at Ballyteigue, Kilmore.
[3] Colclough became involved with the United Irishmen who, seeking to secure for Ireland a representative national government, determined upon a republican insurrection against the British Crown.
[5] After the rebel defeat, he fled with his wife and Bagenal Harvey to the Greater Saltee Island, from whence they planned to escape to republican France.
[4] Found guilty, they were hanged on Wexford bridge on 28 June 1798, their heads afterwards put on spikes and their bodies thrown into the River Slaney.
