A volume of pedigrees of Monmouthshire and Herefordshire and some other families transcribed, with an index of places, in 1904 by John Hobson Matthews ('Mab Cernyw'), Monmouth, from 'Llyfr Baglan'. The original volume was compiled during the years 1600-1607; it was to be edited in full by Joseph Alfred Bradney under the title of Llyfr Baglan or the Book of Baglan (London, 1910).

Fifty-three files of unbound material accumulated by Bradney during the preparation of A History of Monmouthshire and containing press and proof copies, transcripts and abstracts of, and extracts from, manuscripts, deeds and documents, holograph and autograph letters, pedigrees and genealogical notes, press cuttings, etc., generally arranged under parishes. Much of the material is in the autographs of friends and official copyists. This volume contains extracts from the cases of the Committee for the Advance of Money, 1646-1651, and of the Committee for Compounding with Delinquents, 1647-1654; pedigrees transcribed from NLW MS 13166B, formerly Llanover MS E4; an autograph article by Bradney on Welsh parish and other place-names of Monmouthshire; letters, 1905-1917; and miscellaneous genealogical notes and extracts.

A list of names of parishes, hamlets, towns, villages, farms, homesteads, fields, mountains, hills, rivers and brooks in Monmouthshire, compiled, with some notes, by Thomas Morgan (1850-1939), Baptist minister at Skewen.
