Ickford  Ickford is a village and civil parish in the Aylesbury Vale district of Buckinghamshire, England. It is on the boundary with Oxfordshire, about west of the market town of Thame. The River Thame forms both the southern boundary of the parish and Ickford's part of the county boundary with Oxfordshire. A stream that is a tributary of the Thame bounds the parish to the west and north. The village toponym is derived from Old English meaning "Icca's ford". The Domesday Book of 1086 records it as "Iforde". From the 12th to the 14th centuries it evolved through "Ycford", "Hicford", "Hitford", "Ikeford" and "Ickeforde" before later reaching its present form. The Domesday Book records that Miles Crispin held four hides of land at Ickford. Crispin was linked with Wallingford Castle, and through him the manor of Ickford became part of the Honour of Wallingford. In the 13th century the Appleton family were the lower lords of this manor. It is not recorded who held this manor before the Norman Conquest of England. It is recorded that before the Conquest a second manor at Ickford was held by Ulf, a man of Harold Godwinson. The Domesday Book records Robert, Count of Mortain as holding this second manor, with the Benedictine Grestain Abbey as his mesne lord. By 1359 Wilmington Priory in Sussex, an English cell of the abbey, was the mesne lord. By 1377 William de Montacute, 2nd Earl of Salisbury, who had succeeded to some of the de Mortain lands, was Ickford's overlord. Towards the end of the 12th century Bartholomew de Ickford was the lower lord of one of Ickford's manors, apparently that belonging to Grestain Abbey. By the time his great-grandson John held the manor in 1302–03, the family carried the surname "atte Water". William atte Water died in 1313, by which time the family held both manors and they seem to have been merged. Members of the Appleton and Ickford families granted lands at Ickford to Godstow Abbey in Oxfordshire and the Priory of St Frideswide, Oxford. In the 14th century the atte Water family gave land to Bisham Priory in Berkshire.
