Baron Buckhurst

It was first created in 1567 for Thomas Sackville, MP for East Grinstead and Aylesbury. He was later created Earl of Dorset in 1604. That creation became extinct in 1843.

It was next created in 1864 for Elizabeth Sackville-West, Countess De La Warr, the sister of the 4th Duke (and 10th Earl) of Dorset, wife of the 5th Earl De La Warr, with special remainder intended to keep it separate from the earldom. Lady De La Warr was thus succeeded in the barony by her second son. When he also succeeded his brother as 7th Earl De La Warr, the Buckhurst title would have passed immediately to the next brother (Mortimer, later created Baron Sackville), but the House of Lords found such "shifting remainders" invalid (Buckhurst Peerage Case) and the titles became inseparable.
