Gascoyne died on 28 December 1761, and was buried on 4 January 1762 in
Barking Church, in the north aisle of which is a large monument with an inscription, erected to his memory by his four children. His will, dated 20 December 1761, was proved in the P.C.C. 4 January 1762 (St. Eloy, 13). He married Margaret, daughter and co-heiress of Dr. John Bamber, a wealthy physician of Mincing Lane, who purchased large estates in Essex and built the mansion of Bifrons at Barking. A drawing of this house as it appeared in 1794 is preserved in the Guildhall Library copy of
Daniel Lysons's
Environs (vol. iv. pt. i. p. 88). Gascoyne had four surviving children—
Bamber, Joseph, Ann and Margaret. His wife was buried in Barking Church 10 October 1740. Dr. Bamber died in November 1753, and his property
descended in entail to
Bamber Gascoyne I (1725–1791), the eldest son. Bamber Gascoyne entered Queen's College, Oxford (1743); was barrister of
Lincoln's Inn (1750); was M.P. for Malden 1761–63, Midhurst 1765–70, Weobly 1770–1774, Truro 1774–1784, and Bossiney 1784–1786; and was also receiver-general of customs and a lord of the admiralty. On his death in 1791 the Bamber estates descended to his son
Bamber (1758–1824), M.P. for Liverpool 1780–96, who cut off the entail, pulled down the house of Bifrons, and sold the site and park. His daughter and heiress married
the second Marquis of Salisbury, who took the name of Gascoyne before that of Cecil, and became possessed of the Bamber property, worth, it is said, £12000 a year (''
Munk's Roll''). Their son was
Robert Gascoyne-Cecil, 3rd Marquess of Salisbury, three times prime minister. A
mezzotint portrait of Crisp Gascoyne by
James McArdell, from a painting by
William Keable, was published in the
London Magazine for July 1753. There is a smaller and anonymous print, probably of the same date. ==References==
