The parish of Wormshill was originally appended to the village and parish of Boughton Malherbe, since both had the same patron; the patron of a parish was the land-owner who often built the church on the estate and who had the right (known as advowson) to appoint the parish priest. The first recorded patron of Wormshill was Robert de Gatton, who owned the Manor of Wormsell during the reign of Henry III (1207–72). From the Gatton family, the village passed by marriage in the 13th century to Sir Simon de Northwood, whose coat of arms appears in the stained glass of St Giles, the village's only church, and whose name ("Norwood") is given to the farm at the north of the village.
