In April 1817 Viscount Kingsborough’s father secured the Earl of Shannon’s support for his son’s candidature for county Cork. As his father was inclined to opposition and Shannon had just gone over to them, Kingsborough was expected to join the minority. His election speeches gave him sufficient scope for manoeuvre, as he would not commit himself beyond opposition to all taxes and as much support for Catholic relief as was consistent with the constitution. He was returned and emerged as a ministerial supporter, his father having rallied to government.
Kingsborough gave up politics in 1826 to pursue antiquarian studies and became an expert on Mexican history. He died of typhus while imprisoned at Dublin, as security for a debt of his father’s, 27 Feb. 1837.
