The manuscript was later found in the collection of Thomas Wilkins (d. 1699), a Welsh clergyman and antiquarian, who may have borrowed it from the Mansels without ever returning it. In 1697 Wilkins was visited by Edward Lhuyd who spent some time copying a manuscript which might well have been the Red Book. In 1701, two years after Wilkin's death, his son Thomas Wilkins the Younger donated the manuscript to Jesus College, Oxford.
