'Conyers Darcy, 2nd Earl of Holderness (1622 – 13 December 1692) was an English nobleman and Member of Parliament. Conyers Darcy was the eldest son of Conyers Darcy, 8th Lord Darcy of Knayth and 5th Lord Conyers, who was created Earl of Holderness in 1682. ....

Lord Darcy married four times; firstly to Lady Catherine Fane, daughter of Francis Fane, 1st Earl of Westmorland. She thus became Lady Catherine Darcy.

His second marriage took place on 8 February 1650 to Lady Frances Howard (c. 1627-1670), daughter of Thomas Howard, 1st Earl of Berkshire. She thus became Lady Frances Darcy.

'Darcy's third marriage took place in 1676 to Lady Frances Seymour, daughter of William Seymour, 2nd Duke of Somerset. She thus became Lady Frances Darcy.

His fourth and final marriage was on 8 January 1685 to The Hon. Elizabeth Frescheville (1635–1690), daughter of John Frescheville, 1st Baron Frescheville. She thus became Lady Elizabeth Darcy, but would have been known as Lady Darcy and Conyers due to her husband holding a subsidiary title of his father. She became The Countess of Holderness upon Darcy's inheritance of the Earldom in 1689; a title she only held for approximately a year as she died in 1690. ....
