Gregory Fiennes, 10th Baron Dacre (25 June 1539, Hurstmonceaux, Sussex – 25 December 1594, Chelsea, Middlesex, England) was an English courtier.
He was the son of
Thomas Fiennes, 9th Baron Dacre (c. 1515-1541) and
Mary Neville. His father was convicted of the murder of a gamekeeper and hanged like a common criminal at
Tyburn in 1541, and the aftermath the family was stripped of its lands and titles by
Henry VIII.
In the following years, his mother battled to have the properties restored on behalf of her children, and on her ascension in 1558 Queen
Elizabeth restored the title of
Baron Dacre to Gregory, his elder brother Thomas having died of the plague at age 15.
In 1565, he married
Anne Sackville, daughter of
Sir Richard Sackville and Margaret Boleyn. They had one daughter, Elizabeth, who died young. Fiennes, his wife, and daughter, are buried at
Chelsea Old Church within a magnificent marble tomb.
Gregory Fiennes is a sitter with his mother in a significant portrait by
Hans Eworth.
