Sir Oswald Mosley, 5th Baronet (29 December 1873 – 21 September 1928), was a British Army officer, aristocrat, amateur sportsman, and the father of Oswald Mosley, leader of the British Union of Fascists (BUF). His interests were in shooting, boxing, and motor-racing.[1]
Born on 29 December 1873 at Fryers House, near Beaumaris, Anglesey, he was the only son of Sir Oswald Mosley, 4th Baronet, of Rolleston Hall, Rolleston-on-Dove, Staffordshire, and Elizabeth Constance, Lady Mosley (née White), daughter of Sir William White.[2] [3] He gained the rank of Captain in the 1/1st Derbyshire Yeomanry and served in Egypt during the First World War until invalided in 1916. He succeeded his father as 5th Baronet Mosley, of Ancoats (1781, BGB), in 1915.[4]
Mosley became estranged from both his wife and his father, the latter describing him as a "gloomy blackguard".[5] [6] His wife's family, the Heathcotes, thought of him as an "ogre".
He died at his residence, Hilton Lodge, near Derby, on 21 September 1928.[7] His will was proven by probate at the Derby District Registry; his estate valued at £5000, which he left to his ageing mother and sister. He was succeeded in the baronetcy by his eldest son Oswald.
On 12 December 1895, Mosley married Katharine Maud Edwards-Heathcote (1873–1948), the daughter of Capt. Justinian Edwards-Heathcote, of Apedale Hall. She belonged to the wealthy Staffordshire Heathcote family, who held significant property around Newcastle-under-Lyme and Stoke-on-Trent.[8] Their marriage was an unhappy one. Nonetheless, it produced three sons:

| Motto: | Mos legem regit. "Custom rules the law".[11] |
