Brocklehurst was also an Equerry to Queen Victoria from 1899 to 1901 and to Queen Alexandra from 1901[3] to 1910 and an Extra Equerry to Alexandra from 1910 to 1921 and served as Lord-Lieutenant of Rutland between 1906 and 1921. In 1914 he was raised to the peerage as Baron Ranksborough, of Ranksborough in the County of Rutland.[4] The title derived from his seat of Ranksborough Hall at Langham, Rutland, which he constructed in 1893 and which was often visited by members of the royal family. Ranksborough took his seat on the Liberal benches in the House of Lords and served under H. H. Asquith and later David Lloyd George as a Lord-in-waiting (government whip in the House of Lords) from 1915[5] to 1921.[6]
Lord Ranksborough married Louisa Alice Parsons, daughter of the Hon. Laurence Parsons, in 1878. The marriage was childless. He died in February 1921, aged 68, when the barony became extinct. Lady Ranksborough died in 1937.
