Heneage was elected
Member of Parliament for
Lincoln in 1865, a seat he held until 1868. He remained out of parliament until 1880, when he was returned for
Grimsby. When the Liberals came to power under
William Ewart Gladstone in February 1886, Heneage was appointed
Chancellor of the Duchy of Lancaster and vice-president of the Committee of Agriculture and sworn of the
Privy Council. However, he resigned these offices in April after disagreeing with Gladstone over
Irish Home Rule. He joined the
Liberal Unionist Party the same year. Heneage lost his Grimsby seat at the
1892 general election, but was successfully returned for the same constituency in a by-election the following year. He was Chairman of the Liberal Unionist Council from 1893 to 1898. In June 1896 he was elevated to the peerage as
Baron Heneage, of Hainton in the County of Lincoln. He was a regular contributor in the
House of Lords, making his last speech in June 1920 at the age of 80. Apart from his political career Heneage served as vice-chairman of Lindsey
Quarter Sessions and as High Steward of Grimsby. ==Family==
