DB records a priest at Brockworth; the manor was held by Hugo Asinus, an associate of William fitz Osbern (Bartleet, 133--4).
Roger de Chandos I gave estates in Herefordshire to Lanthony Secunda, and Richard of Brockworth, his steward, gave land in Brockworth about the time of the dedication of the priory in 1136 (Langston, 16). Shortly afterwords, Roger's son, Robert de Chandos, granted to the priory the church of Brockworth, together with its existing half a hide of land. He supplemented this grant with the gift of his house, by the churchyard, and the small estate of Northwood in Brockworth. According to his deed, he would also release the church of all services owed to him on its dedication. This would imply that the church was then being rebuilt in stone. A charter of Roger's other son, Roger II de Chandos, dated Sunday, 8 April, 1142, not only recorded further gifts to the priory, but also provides the important detail that the church had been dedicated by Simon, bishop of Worcester. English translations of both charters, from a Lanthony cartulary then in the possession of Sir Thomas Phillipps (and still in private possession), are printed in Bartleet 1882--3, 138--19.
Bartleet provides an illustration of the top of the tower before its destruction in 1847 (Bartleet 1882--3, 167, fig. 33).
Verey et al. 2002 says that the core of the central tower (not visible from the outside) is from the church consecrated in or before 1142. Almost all of the church was rebuilt in the 14thc.
Brockworth Court, adjacent to the church, was built for one of the last priors of Llanthony Secunda, and has a building called ‘John the Priest’s house'. The deed of Roger II de Chandos refers to his gift of the house of John the priest, and this building may thus contain early foundations (not seen). The abbot of St Peter’s Gloucester had purchased land in Brockworth in the 13thc. (VCH ii. 53--61).
