Description: Nephew of Sir Thomas Pelham Holles, 1st Duke of Newcastle, who died without heir. Born 16 April 1720, died 22 February 1794. Henry Fiennes Pelham-Clinton succeeded his uncle as 2nd Duke of Newcastle under Lyne (known until 1768 as the 9th Earl of Lincoln). Married to Henry Pelham's daughter Catherine. He was High Steward of Westminster from 1759 until his death. The title of Newcastle-under-Lyne (or Line later known as Lyme) was granted in 1756 to Thomas Pelham-Holles (1693-1768), fourth duke of Newcastle-upon-Tyne (a title deriving from the time of William Cavendish in 1665 and proceeding thereafter by descent and re-creation). Pelham-Holles had no male issue and the new title enabled the estates to descend to his nearest male heir, his nephew by marriage, Henry Fiennes Clinton ninth Earl of Lincoln (1720-94), who became second duke of Newcastle-under-Lyne in 1768 (the title of Newcastle-upon-Tyne ceasing with Pelham-Holles' death)
