Catherine Tylney-Long

Her only brother, James, had inherited their father's fortune but died just short of his eleventh birthday in 1805, meaning that the vast estates (see list at Draycot Cerne article) gathered by the 7th Baronet in Essex, Hampshire and Wiltshire and financial investments in hand worth £300,000 (equivalent to about £30,800,000 in 2023) devolved to Catherine.

She thus became known in fashionable London society as "The Wiltshire Heiress"[2] and was believed to be the richest commoner in England.

[4] The couple married on 14 March 1812, but his extravagance, arrogance and cruelty meant the marriage was an exceedingly unhappy one.

[4] William gained an appointment as Gentleman Usher to George IV in 1822 (rendering him immune to arrest for debt) and left Britain to escape his creditors around 1823.

[4] She died at age 35 in Richmond, Surrey, leaving their children, William, James and Victoria, in the care of her two unmarried sisters, Dorothy and Emma.
