At various times in his life he was able to study the records in the
library of Sir Robert Cotton, in
Skipton Castle and in the
Tower of London. He collected a vast store of materials for a history of
Yorkshire, a
Monasticon Anglicanum, and an English baronage. The second of these was published with considerable additions by Sir
William Dugdale (2 vols., 1655 and 1661). The manuscripts were left to
Thomas Fairfax, 3rd Lord Fairfax of Cameron, who by his will bequeathed them (160 volumes in all) to the
Bodleian Library at
Oxford. Portions have been printed by the
Yorkshire Archaeological Society (Dodsworth's
Yorkshire Notes, 1884) and the
Chetham Society (copies of Lancashire
inquisitions post mortem, 1875–1876). Dodsworth was aided in his study of early Yorkshire by
Thomas Levett, a native of
High Melton, Yorkshire and
High Sheriff of Rutland, who came into possession of the
Chartulary of St. John of Pontefract, a collection of early Yorkshire documents kept by monks at the
Cluniac abbey. In 1626–27 Levett gave the documents to Dodsworth. How Levett came to possess them is unknown, but the Levetts had been prominent in Yorkshire for centuries, and had once controlled
Roche Abbey. ==References==
