The Smith, later Dodsworth, later Smith-Dodsworth baronetcy, of Newland Park in the County of York, is a title in the Baronetage of Great Britain. It was created on 22 January 1784 for John Silvester Smith, of Newland Park, Yorkshire. He married Henrietta, daughter of John Dodsworth, of Thornton Watlass Hall, Yorkshire, and sister and heiress of Frederick Dodsworth.
The 2nd Baronet assumed in 1821 by Royal licence the surname of Dodsworth in lieu of his patronymic. The 4th Baronet assumed the surname of Smith-Dodsworth. The 8th Baronet, an English-New Zealand naturalist, botanist, and plant conservationist, died on September 21, 2012.
The heir apparent is the present holder's only son Matthew David Smith-Dodsworth (born 2002).
The Dodsworth family is descended from Lionel, Duke of Clarence, third son of King Edward III and Philippa of Hainault. The Thornton Watlass estate was acquired in 1415 by Thomas Dodsworth. Sir Edward Dodsworth, Commissary-General to the Parliamentary Army, Matthew Dodsworth and the antiquary Roger Dodsworth were later members of the family.
