[2] The ancient parish of Fisherton de la Mere formed a detached part of the Warminster hundred of Wiltshire.
[4][5] The former parish was a rough oblong stretching both north and south up into the downland on each side of the river, each slope running down from an altitude of about 600 feet.
[4] The name Delamere, Delamare, or de la Mere, refers to the family of Nunney Castle, Somerset,[9] who owned the manor in the Middle Ages, and whose name was spelt in all of those ways.
[10] When his niece and heiress Eleanor Delamare died in 1413, Fisherton passed into the Paulet family and thus to the William Paulet who was Lord Chamberlain and Secretary of State to Henry VIII, and Lord High Treasurer to Edward VI, Lady Jane Grey, Mary I, and Elizabeth I.
[13] The parish registers survive in the Wiltshire and Swindon History Centre for the following dates: christenings 1561–1895, marriages 1566–1992, and burials 1569–1992.
[14] Almost all of the present village of Fisherton de la Mere is now part of the parish of Wylye.
