Lionel Damer was considered for East Grinstead in 1783. On 9 May Lord Sackville wrote to General Irwin, who was leaving Parliament:
Like his brother George, Lionel Damer was closely connected with Lord Fitzwilliam. On 27 July 1784 he told Fitzwilliam he was willing to stand for Peterborough if a vacancy occurred, but could not pay more than £1,500 for his seat.
He died 28 May 1807.
