Ker’s father, of a Scots family settled in Antrim, migrated to London. Ker reversed the process and purchased an Antrim estate in 1780. He was worth nearly £4,000 p.a. there in 1802.
Ker supported Addington’s ministry. In his first known speech, 28 July 1803, he claimed that martial law had benefited Ireland. From the Irish viewpoint, he could not be quite happy about the export tax on linen, 7 Mar. 1804, and on 3 May presented petitions against it. He grew restive when a debate on these was postponed for the benefit of Pitt’s defence bill, 31 May, spoke of ‘the late administration which he rejoiced in the recollection of having supported’ and of the ‘delay, indecision, want of energy and promptitude’ of Pitt’s new one. He opposed the additional force bill, June 1804, and wrote to Addington from Ireland to confirm its failure there, 22 Oct.
As Lord Sidmouth was a member of it, he was well disposed to the Grenville ministry. He opposed Paull’s motion for copious papers on Wellesley’s Indian administration, being confident that most Members would not read them and that they might disclose information to the enemy, 17 Mar. 1806. He saw no reason why foreigners investing in British stock should not pay property tax and asked for statistics on the subject, 28 Apr., 12 May 1806.
Ker was not in the next Parliament, though it is surprising that he did not seek election. He had become a trustee of the linen board. He died 24 Sept. 1822.
