A volume containing a late nineteenth or early twentieth century transcript of the Taicroesion Pedigrees, described on the title page as 'A most valuable copy transcribed by a Solicitor and examined and compared with the original, so it is the most reliable copy extant'. There are, however, some errors of transcription and some additions. There is a table of contents at the beginning and the pedigrees are followed by a list of the names of the high sheriffs for Caernarvonshire, 1540-1796, written in a different hand.

A copy, in three volumes, of the history of the Welsh side of the donor's family, and that of his late wife, Rosemary, who hailed from Devon, the results of research undertaken between 1979 and 2001, entitled 'The Mattabel Inheritance'.
