Neville Blyth (March 1825 – 15 February 1890) was a South Australian colonial politician. Blyth was some two years younger than his brother Arthur Blyth, was also born in a suburb of Manchester, educated at King Edward's Grammar School under the Rev. Dr. Lee (later the first Bishop of Manchester), and with his family sailed to South Australia in 1839.Early in the forties Neville joined his brother Arthur at their father's ironmonger business, and the two were actively engaged in the trade up to 1865. At his father's death Neville Blyth was sole executor of his estate and, characteristically, first repaid debts his father had incurred in England but legally wiped out by his insolvency.
