Aguillon family

The Aguillon family, of French origin, were feudal landowners in England who held estates in several southern counties from before 1135 to 1312. Surviving records suggest various branches which all ended without male heirs, the lands going to daughters or sisters and their husbands. The family seems to have been initially associated, perhaps as under-tenants and maybe through marriage, with the Marmion family, witnessing charters alongside them in Normandy in 1106 and later occupying their land in England.

The English branches may spring from William Aguillon (died after 1147), a descendant of the viscounts of Chaumont, who was seigneur of Trie near the French border with Normandy around 1119 and died on the Second Crusade. He married Margaret of Gisors and their son and heir was Enguerrand (died about 1196). Manser may have been a younger son.

In England, family members can be found in four apparent groups but establishing definite connections between the four groups may be impossible.
