Margaret was the heiress of her brother Roger Tuckfield (c.1685-1739), MP for the family's pocket borough of Ashburton, following their purchase of the manor of Ashburton in 1702. The Rolle family of Heanton Satchville was a junior, but nonetheless wealthy, branch of the Rolle family of Stevenstone in Devon, one of the largest landowners in Devon, descended from George Rolle (d.1552), MP, who acquired lands following the Dissolution of the Monasteries. She was also heiress to her paternal grandmother, Lady Arabella Rolle, née Lady Arabella Clinton, a daughter and co-heiress of her brother Edward Clinton, 5th Earl of Lincoln, 13th Baron Clinton (d. 1692), who had been the wife of Robert Rolle (d. 1660), MP, of Heanton Satchville.
