The
Domesday Book of 1086 records two
Norman-held
manors at Sibford Gower. In 1086 William, son of Corbicion held 10
hides there, which was assessed as one
knight's fee. By 1122
Henry de Beaumont, 1st Earl of Warwick held this manor. The last known reference to its
feudal overlordship was under
Richard Neville, 16th Earl of Warwick in 1458. By 1190 the
feoffee of the Beaumont manor was a Norman, William Goher. In the 1220s the family seem to have rebelled against
the Crown and forfeited their lands, but by 1242–43 Thomas Goher had recovered the estate. The "Gower" part of the village's
toponym is derived from a variant of "Goher". The other manor was of 11 hides and was held by
Hugh de Grandmesnil. His son
Ivo de Grandmesnil mortgaged the family estates to
Robert de Beaumont,
Count of Meulan in 1102. Ivo died that same year, and the Crown allowed de Beaumont to keep the Grandmesnil estates. In 1204
Robert de Beaumont, 4th Earl of Leicester died childless, leaving Sibford Gower to his younger sister Margaret, wife of
Saer de Quincy. When their son
Roger de Quincy, 2nd Earl of Winchester died in 1264 Sibford Gower passed to his eldest daughter Ellen or Helen, wife of
Alan la Zouche. She left it to their grandson
Alan la Zouche, 1st Baron la Zouche of Ashby, who left it to his daughter Maud, wife of
Robert de Holland, 1st Baron Holand. In 1328 Holland was executed for treason, but his family kept the manor and it passed to his son
Thomas Holland, 1st Earl of Kent. He left it to his niece Maud, wife of John Lovel, 5th Baron Lovel, who held the manor in 1374. It descended with his heirs until John Lovel, 8th Baron Lovel, who died in 1465. No subsequent records of the overlordship of this manor are known. His son
Francis Lovell, 1st Viscount Lovell supported
Richard III in the
Wars of the Roses and fought at the
Battle of Bosworth Field. Lovell survived Richard's defeat but
Henry VII ordered the forfeiture of all his titles. In about 1225 William of Wheatfield, feoffee of the de Quincy manor, granted land in Sibford Gower to the
Knights Templar, who had held land in neighbouring Sibford Ferris since the middle of the 12th century. Slightly later the elder Alan la Zouche also granted land to them. In 1314, when the last of the
Knights Templar in England were suppressed, their estate at Sibford Gower was 10
yardlands and was assessed as of a knight's fee. Sibford Gower
Manor House was built in the 17th century.
Frank Lascelles, who grew up in the village, had it substantially remodelled between 1907 and 1915. Until 1773 Sibford Gower had a single
open field of 80 yardlands. In 1774 the
inclosure award for Sibford Gower divided between 48 landholders. The largest award was to
New College, Oxford, which had held the rectory of
Swalcliffe since 1389 and over the years had extended its estates into Sibford Gower. ==Meeting-house, chapel and church==
