Derek Brewer calculated that there must have been at least six now-lost manuscripts that provided the source material for the Thornton MS, which evidences a wide "spread of manuscripts now lost." Sir Percyvelle, for instance, was originally composed in the fourteenth century in a north-east Midland dialect, and one version would have traveled north to be copied by Thornton while another traveled south to be referenced by Geoffrey Chaucer in Sir Thopas.
