Marsh Gibbon was described in 1806 in "Magna Britannia" as follows:
MARSH-GIBWEN, in the hundred and deanery of Buckingham, lies on the borders of Oxfordshire, about four miles and a half to the east of Bicester. It received its additional name from the ancient family of Gibwen, who were of considerable consequence in the county, in the thirteenth century, and had estates in this parish. The principal manor was given by Robert, Earl of Cornwall, to the abbey of Grestein, in Normandy. About the year 1365, having been seized by the crown as the property of an alien monastery, it was granted to the De la Poles. William De la Pole, Duke of Suffolk, and Alice, his wife, gave it to the hospital of Ewelm, in Oxfordshire, the mastership of which was annexed in 1603 to the Regius professsorship of physic, in the university of Oxford, in whom, jointly with the grammar-master and thirteen poor men, the manor is now vested, but all the business relating to it, is transacted in the name of the two chaplains and thirteen poor men. Near the manor-house are some slight traces of entrenchments, supposed to have been thrown up by the parliamentary army, when they marched to Marsh-Gibwen, in the month of June 1645.
The Bury-manor, or manor of Westbury, in this parish, belonged also to the abbey of Grestein, (by grant from the Montacutes.) Having escheated to the crown, as the property of an alien house, it was given by King Edward IV. to the Company of Cooks, in London, who sold it, in 1530 to Robert Dormer: it has since passed through several hands, and is now the property of Mr. Dixon. The advowson of the rectory belonged formerly to the Abbey of Grestein, it is now in the crown.
