George Osborne, 8th Duke of Leeds

Lord Leeds was born at Gogmagog Hills, Cambridgeshire, the eldest son of Lord Francis Osborne and his wife, The Hon. Elizabeth Eden.[1] Lord Leeds's father, Lord Francis, was the second son and youngest child of Francis Osborne, 5th Duke of Leeds, and his wife, the former Lady Amelia Darcy.[2][3] Lord Leeds's mother was the daughter of William Eden, 1st Baron Auckland.

In 1832 his father was created Baron Godolphin,[3] upon which George became known as The Hon. George Osborne.[1] When the 1st Baron Godolphin died in 1850, George succeeded his father and became the 2nd Baron Godolphin of Farnham Royal co. Buckingham.[1][3] Nine years later, George's cousin, the 7th Duke of Leeds, died without issue; George therefore inherited the Dukedom of Leeds,[1][3][4] thus becoming styled His Grace The Duke of Leeds. With the Dukedom of Leeds, George also inherited the titles Earl of Danby co. York, Viscount Osborne of Dunblane, 4 May 1859, Baron Osborne of Kiveton co. York, Marquess of Carmarthen, Viscount Latimer of Danby co. York, and Baronet Osborne of Kiveton co. York.[1] Though the dukedom had passed to George, the Baronies of Conyers and Darcy de Knayth and the Portuguese countship of Mértola were passed to his cousin Sackville Lane-Fox. Lane-Fox was the son of George's father's elder sister, Mary Pelham, Countess of Chichester; and as those peerages allowed for succession in the female line, they passed to Lane-Fox.[3][5][6] Godolphin barony and the dukedom remained united until the death of the last Duke of Leeds in 1964, when both titles became extinct.[3][4]

On 21 October 1824, he married Harriet Emma Arundel Stewart at the British Embassy in Paris.[1] She was an illegitimate daughter of Granville Leveson-Gower, 1st Earl Granville, by Lady Henrietta Frances Spencer, wife of the 3rd Earl of Bessborough. Harriet Stewart was thus a maternal half-sister of Lady Caroline Lamb.

With Harriet Stewart, he had eight children:[1][7]

Frances Georgiana Pitt-Rivers, daughter of George Pitt-Rivers, 4th Baron Rivers of Sudeley Castle and Lady Susan Georgiana Leveson-Gower (herself a daughter of Granville Leveson-Gower, 1st Earl Granville); had issue.[8] He was succeeded in the dukedom by his second surviving son, George Osborne, 10th Duke of Leeds.[9]
