John Conningsby died in 1544 and entailed the house to his wife, Elizabeth, during her lifetime. Elizabeth remarried to William Dodds. On Elizabeth's and subsequently William's death, the house reverted to John's son, Henry in 1576, which he then demolished and built a new mansion house between 1576-1578. Tree-ring dating of the main roof timbers confirms these dates. During the ownership of Thomas Coningsby, a Royalist leader in Hertfordshire, the house was plundered by the Parliamentarians. Later North Mymms Park belonged to the Hyde family. The house is famous for its collection of tapestries and for its panelling and fittings. An early 17th-century painted frieze of the "Nine Worthies" was rediscovered in the 20th century. North Mymms House was a location for the 1983 film The Wicked Lady, starring Faye Dunaway as a bored aristocratic lady who takes up highway robbery, while the exterior appeared in Agatha Christie's Marple'''s The Mirror Crack'd from Side to Side as the house of Marina Gregg. Bell Bar Brookmans Park: The park includes the former park of Gobions (demolished), once the property of Sir Thomas More, and around the turn of the 19th century to an East India merchant, Thomas Holmes, whose daughter became the novelist Ann Doherty.
