 Patrick Sims-Williams suggests that the foundation by Oswald may also represent an oral tradition at Pershore, as its archives were probably destroyed in fires of 1002 and again in 1223.In the 9th century, Pershore comes to light again as a minster under the patronage of Mercian kings.In other charters contained in the Gloucester register, Coenwulf (r. 796-821) and Burgred are recorded as having been patrons of Pershore.
