A notebook in the hand of Thomas Edward Ellis (1859-99) containing notes and extracts mainly relating to Morgan Llwyd (1619-59) and the religious background of the sixteenth and seventeenth centuries, probably compiled in connection with the preparation of Gweithiau Morgan Llwyd o Wynedd, ed. Thomas E. Ellis (Bangor and London, 1899). The second volume of Gweithiau Morgan Llwyd o Wynedd was published in 1908 and edited by J. H. Davies, who states (p.v) that T. E. Ellis had left a large number of disconnected notes which he had found very useful in preparing his work.
