Walter Devereux, 1st Earl of Essex
Walter Devereux was the eldest son of Sir Richard Devereux, who was created a Knight of the Bath on 20 February 1547 and died that same year, in the lifetime of his father, The 1st Viscount Hereford. Walter Devereux's mother was Lady Dorothy Hastings, daughter of The 1st Earl of Huntingdon and Anne Stafford, said to have been a mistress of Henry VIII. Through his paternal ancestry he was related to the Bourchier family, to which previous Earls of Essex had belonged: John Devereux, son of Walter Devereux who died at the Battle of Bosworth, married Cecily Bourchier, sister of Henry Bourchier, 2nd Earl of Essex.
Walter Devereux (died 1402)
Walter Devereux was born about 1361, the son of Sir Walter Devereux (died c. 1383) of Bodenham and a woman named Maud. His father was the cousin of John Devereux, 1st Baron Devereux of Whitchurch Maund, and they were close allies. Walter's grandfather, William Devereux of Bodenham, had made land concessions in Bodenham Parish (Hereford) to John Devereux about 1360, and throughout his life Baron Devereux appears to have promoted the careers of his cousin's family in the royal household.
