Glympton is presumed to have been held by Edward, whose boundary touched the neighbouring parish of Wootton in 958, and later by Aegelric of Glympton who witnessed a charter c.1050. In 1066 Glympton, together with estates in Wootton, Finmere and Hethe, was held freely of Edward the Confessor by Wulfward the White, who survived the Conquest, but by 1086 it was part of the fee of Geoffrey, Bishop of Coutances. It presumably passed with Geoffrey's other lands to his nephew Robert de Mowbray, earl of Northumberland, and was forfeited to the Crown on his rebellion in 1095. The Bishop's tenant in 1086 was William, perhaps the ancestor of the next recorded lord, Sir Geoffrey de Clinton (Henry I's chamberlain), who first appears c.1110, and certainly held Glympton by 1122. He gave Glympton to his brother William, who was succeeded by his son Ralph. From Ralph it went to his brother Jordan de Clinton (d.1189), who had exchanged it with Geoffrey's grandson, Henry de Clinton.
The church was in existence by the early 12thc when Manasser Arsic gave it 1.5 hides in Ludwell (Ledwell, nearby). Geoffrey de Clinton gave Glympton church to his new foundation, Kenilworth priory, in 1122. The Priory’s right to it was challenged twice, unsuccessfully (VCH).
The original dedication was to St Laurence, but it was changed to St Mary by the early 18thc, although the parish wake was still kept on or near St Laurence’s day (VCH). However, Frances Arnold-Forster (1899) does not recognise the early dedication to St Laurence. The church is now in the United Benefice of Wootton, Glympton and Kiddington.
