The arms are those of Phipps impaling those of Liddell, as borne by Constantine Henry, Earl of Mulgrave, born in 1797, who succeeded to the Earldom on the death of his father in 1831 and who was created Marquess of Normanby in 1838. He married in 1818 the Hon. Maria Liddell, eldest daughter of Thomas Henry, 1st Lord Ravensworth. He was Governor General of Jamaica from 1832 to 1834, Lord Privy Seal in 1834, Lord Lieutenant of Ireland from 1835 to 1839, Secretary of State for the Colonies in 1839 and for the Home Department from that year to 1841. From 1846 to 1852 he was Ambassador to France and from 1854 to 1858 he was Envoy to Tuscany.

Lord Redesdale in his Memories contrasts his "Turveydrop-like pomposity" in a dispute with the Tuscan Government with the simple, sober dignity of Lord Lyons. Greville, in his Memoirs, January 28, 1852, remarks: "His vanity is very amusing, for he talks of his great influence, and the respect and consideration in which he was universally held, when everybody knows that there never was an Ambassador so generally disliked and despised."
