The
Domesday Book of 1086 records the manor as held by Queen Matilda. Before the
Norman Conquest it had been a possession of
Brictric, a powerful
thane based in Gloucestershire. After the death of Queen Matilda the manor was granted by the king to
Tetbald FitzBerner, one of King William's knights. The manor derives its appellation "Burnell" from a corruption which has developed over the centuries of the name "Berner". From the 15th century the manor was held by a branch of the
Denys family. Thomas Denys (died 1498) of Holcombe Burnell married Janera Loveday, daughter of Philip Loveday of
Sneston in Suffolk, and their son was Sir
Thomas Denys (c. 1477 – 1561), a prominent lawyer who served as
Sheriff and MP for
Devon. He married twice, firstly to Anne, widow of Thomas Warley a Treasury official, and secondly to Elizabeth Donne, widow of Sir
Thomas Murfyn,
Lord Mayor of London. Sir Thomas is notorious as having supervised the burning at the stake of the Protestant martyr
Thomas Benet in Exeter in January 1531/2. His eldest son was Sir
Robert Dennis (died 1592), MP for Devon in 1555 and Sheriff of Devon, who acquired
Bicton House. According to
W. G. Hoskins, the Easter Sepulchre in the church is his tomb and monument. Sir Robert married Mary Blount, a first cousin of
Lady Jane Grey. In March 1591 he founded the
Livery Dole Almshouses in Heavitree Road, Exeter. Sir Robert's eldest son and heir, Sir Thomas Denys married Anne Paulet, daughter of
William Paulet, 3rd Marquess of Winchester, and left two co-heiresses, Anne Denys who married Sir Henry Rolle (died 1616) of
Stevenstone, and Margaret Denys (died 1649) who married
Sir Arthur Mainwaring of Ightfield, Shropshire. ==Principal houses==
