Sir Matthew White Ridley, 3rd Baronet (18 April 1778 – 14 July 1836) was a politician in the United Kingdom. He was Member of Parliament (MP) for Newcastle upon Tyne from 1813 until his death in 1836.
He inherited the baronetcy on the death in 1813 of his father Matthew, and was in turn succeeded by his eldest son Matthew. His younger son, George, also sat in Parliament for Newcastle (1856–1860). His daughter Janetta Maria Ridley married Isaac Cookson and emigrated with him to New Zealand where her husband became a Member of Parliament.[1] [2]
