Writing in 1931, Victor Strode Manley, as part of his Regional Survey Of Warminster And District, made the following notes about Stockton:
“The two western bays of nave arcade are late Norman; the eastern bay is 14th century. The tower is 13th century cornice and parapet. The west end of the north aisle is 13th century; the rest rebuilt in 1842. The south wall of the chancel is 13th century with “low-side’ window; the other walls were rebuilt in 1840. The south aisle is 14th century; the recumbent female figure lying on her left side is probably the foundress of the Chantry (aisle). The clerestory of nave and roof are 15th century.
Notice especially the solid wall dividing the nave from the chancel with only a narrow doorway and a squint on each side, apparently built in the 15th century. The east end of the north aisle was remodelled to receive the Elizabethan tomb of the founder of Stockton House. The font is Norman and the pulpit Jacobean. (See Wiltshire Archaeology Magazine, xii, 114; xx, 121; xvii, 251), (From programme, Wiltshire Archaeological Society visit to Warminster, 1931).
Heath adds: “The church is Trans-Norm. The roof of the north aisle is of carved cedar wood. Here is a canopied tomb to John Topp (died 1640), with effigies of himself and his wife and family. In the south aisle is an altar-tomb to Jerome Poticary, who, in spite of his name, was, like Topp, a wealthy and benevolent clothier who built another manor-house here, now a farmhouse.”
The Bishop of Worcester is the lord of the manor.
