Reference: Peniarth MS 54ii
A late 15th to the 16th century manuscript, seemingly belonging to Peniarth MS 54i, and containing poetry of Hywel Cae Llwyd and others, and pedigrees. The cywyddau of Hywel Cae Llwyd and Hywel and Ieuan Swrdwal are written in the same hand as that which cited the works of Hywel Cae Llwyd and Hywel Swrdwal in Peniarth MS 54i. A detailed list of the manuscript's contents may be found in J. Gwenogvryn Evans, Report on Manuscripts in the Welsh Language, vol. I (London, 1898-1905), 409-420.
