Cotter’s father, a senior partner in the Cork bank of Cotter and Kellet, sat in the Irish parliament for nearly 25 years. His political chief was Lord Shannon, and after he had supported the Union his patron pressed government to reward him. Lord Hardwicke, noting that he resided in England, suggested an inspectorship of Irish tontines. In 1807 the Cork bank failed, with liabilities of £420,000.
Cotter junior came in for Mallow in 1812 at Lord Shannon’s instigation.
His tenure of Mallow was precarious owing to his inability to afford a contest and his anti-Catholic stance. It is true that on 2 Mar. 1813 he did not vote on Catholic relief, ‘because he was afraid that the Catholics would outbid him in the sale of an estate which he particularly wished to purchase’. For this the viceroy labelled him a ‘shabby fellow’.
