JOHN WILSON CROKER, ESQ. is a native of Ireland, and son of a gentleman who enjoyed a considerable estate in Dublin. He was born in that city in 1781; and having studied in Trinity college, Dublin, was entered of the society of Lincoln's Inn; and in 1802 was called to the bar in Ireland. At the general election in 1807 he stood candidate for Downpatrick, in Ireland, and after a warm contest, both in the borough and before a committee of the House of Commons, he was successful. In 1809 he took a very active part in the inquiry into the affair of the duke of York and Mrs. Clarke, who proved herself a full match for Mr. Croker, although she was at the bar, and he at his seat in the house. The zeal he showed in this affair recommended him so much to his highness and the ministers, that he was appointed secretary for Ireland during the absence of Sir Arthur Wellesley, which office he filled for the rest of the year, when he was appointed first secretary to the board of admiralty, an appointment which he still holds. He has since been member of parliament for the borough of Athlone, but now sits for Yarmouth, in the Isle of Wight. Mr. Croker has been often the object of attack, both of the opposition in the House of Commons, and of the opposition papers, provoked by the air of contempt, with which he often speaks. He is the author of some literary productions of merit, published anonymously, but admitted to be from his pen: as Familiar Letters to the Irish Theatre, 1803; a Letter written and intercepted from China; Sketch of the Past and Present State of Ireland; and The Battle of Talavera, a poem; and he is considered to be one of the writers in the Quarterly Review, and other party publications.
