This group of manuscripts, after a collation with Penrhos Mss 20-28, appear without much doubt to have been written by Dr Edward Wynn of Bodewryd, Chancellor of Hereford (1707- 1754), and cousin to Henry Morgan of Henblas. The only other likely author was Dr Robert Morgan (who must, after collating the script with Penrhos I, 639-674, be pronounced as the author) rector of Llanddyfnan after 1701, uncle to Henry Morgan on the paternal side 1718
