--------
Humphrey III de Bohun (before 1144 – ? December 1181) was an
Anglo-Norman nobleman and general who served
Henry II as
Constable. He was the son of
Humphrey II de Bohun and
Margaret of Hereford, the eldest daughter of the erstwhile constable
Miles of Gloucester. He had succeeded to his father's
fiefs, centred on
Trowbridge, by 29 September 1165, when he owed three hundred marks as
relief. From 1166 onwards, he held his mother's inheritance, both her Bohun lands in
Wiltshire and her inheritance from her late father and brothers.
As his constable, Humphrey sided with the king during the
Revolt of 1173–1174. In August 1173, he was with Henry and the royal army at
Breteuil on the continent and, later that same year, he and
Richard de Lucy led the sack of
Berwick-upon-Tweed and invaded
Lothian to attack
William the Lion, the
King of Scotland, who had sided with the rebels. He returned to England and played a major role in the defeat and capture of
Robert Blanchemains, the
Earl of Leicester, at
Fornham. By the end of 1174, he was back on the continent, where he witnessed the
Treaty of Falaise between Henry and William of Scotland.
According to
Robert of Torigni, in late 1181 Humphrey joined
Henry the Young King in leading an army against
Philip of Alsace, the
Count of Flanders, in support of
Philip II of France, on which campaign Humphrey died.
He was buried at
Llanthony Secunda.
Sometime between February 1171 and Easter 1175 Humphrey married
Margaret of Huntingdon, a daughter of
Henry, Earl of Northumbria, and widow since 1171 of
Conan IV, Duke of Brittany. Through this marriage he became a brother-in-law of his enemy, William of Scotland. With Margaret he had a daughter, Matilda, and a son,
Henry de Bohun, who in 1187 was still a minor in the custody of Humphrey's mother in England and who was created Earl of Hereford. It has been suggested that Humphrey's widow was the Margaret who married
Pedro Manrique de Lara, a Spanish nobleman, but there are discrepancies in this theory.
