William Green (1775–1860) was a player of the Northumbrian smallpipes, and the Piper to the Duchess of Northumberland from 1806 until 1849. He was assisted in this role by his nephew Robert Nicholson (1798–1842), and his son William Thomas (Tom) Green (1823–1898). Tom then succeeded his father as Ducal Piper until 1892. Father, nephew and son thus held some of the most influential piping roles in the county for a period of almost ninety years.
