He had one sister, Anne, Marchioness Berkeley (died 10 September 1497), who married secondly to Sir Thomas Brandon.

He was also known as Baron Dacre of the South owing to his family seat of Herstmonceux Castle being in the county of Sussex.

[3] The marriage produced three sons and a daughter:[4] He died on 9 September 1534 at the age of 62.

He was succeeded by his eldest grandson, Thomas Fiennes, as his sons had predeceased him.

The tomb set up for the 8th Baron Dacre and his son at All Saints Church, Herstmonceux, known as the Dacre Tomb,[5] is thought to have made use of effigies from an older monument intended for Thomas Hoo, Baron Hoo and Hastings (1396-1455) and his younger half-brother, also Sir Thomas Hoo (born 1416).
