The Newtons of Haydon derived their fortune from a Grantham usurer, whose money was used to acquire the reversion of the estates and baronetcy of an unrelated insolvent namesake, Sir John Newton, 1st Bt., of Barr’s Court, Gloucestershire, the last of his line.1N and Q. (3 ser.), i. 190. In 1725 Michael Newton inherited another fortune from his maternal uncle, Sir Michael Warton, on whose interest he was returned for Beverley in 1722, before transferring in 1727 to Grantham, which he represented for the rest of his life. Though one of the wealthy commoners invested with the order of the Bath when Walpole revived that order in 1725, he voted against the Government in every recorded division till his death, 6 Apr. 1743, when the baronetcy became extinct.
