Westport in Malmesbury / Westtport St. Mary

The Victoria County History (Wiltshire, vol. 14, 1991) notes: "there was a church at Westport in the late Saxon period [...] The small pre-Conquest church, of which the nave survives, stood north of Bristol Street. It was apparently known in the later Middle Ages as St. Helen's, and was presumably converted for other uses after the Dissolution. [...] The church of St. Mary, standing and so called in the later 12th century [...] was destroyed during the Civil War [...] A small church [...] was built after the war [...] After it was rebuilt c. 1840 [...] it had an undivided chancel and nave with a south aisle of five bays and a western bellcot. [...] Registers of baptisms and burials survive from 1678 [...] A western gallery was later removed, and the arcade was blocked when the church was converted to a hall." [NB: we have no information from the fonts of the two medieval churches].
