De Capell Brooke baronets
The de Capell-Brooke Baronetcy, of Oakley in the County of Northampton, was a title in the Baronetage of the United Kingdom. It was created on 20 June 1803 for Richard de Capell-Brooke, a bencher of the Inner Temple and for 30 years a Colonel of the Northamptonshire Militia. Born Richard Supple, he was the son of Richard Supple, of Ahadoe, who in the 1750s married Mary, daughter of Arthur Brooke, of Great Oakley, Northamptonshire. In 1797 he inherited the Great Oakley estate from his great-uncle, Wheeler Brooke, and assumed at that time by sign manual and in obedience to the testamentary injunction of his great-uncle the surname Brooke as well as the original surname of his family, de Capell. He was succeeded by his eldest son, the second Baronet, who was a noted travel writer and Fellow of the Royal Society. The fifth Baronet was High Sheriff of Rutland in 1899, a deputy lieutenant of Northamptonshire and a justice of the peace and also unsuccessfully stood three times for the parliamentary seat of East Northamptonshire. On 4 July 1939 he was elevated to the Peerage of the United Kingdom as Baron Brooke of Oakley, of Oakley in the County of Northampton. The barony became extinct on his death in 1944 while he was succeeded in the baronetcy by Sir Edward de Capell-Brooke, the fifth Baronet. The baronetcy became extinct on the latter's death in 1968.
