Pedigrees of English baronial families, as well as of other land-owning families of the north of England (esp. Yorkshire), compiled by Roger Dodsworth and substantiated by references to and excerpts from the other volumes of his collection. The pedigrees are not limited to the male line, but give the ancestry and posterity of married heiresses, e.g. the elaborate pedigree of the Stapletons (fols. 19v-29) is interwoven with pedigrees of the various families whose lands they inherited and whose arms they quartered: comparatively few are brought down to a later date than the 15th cent. Each volume is preceded by an alphabetical index of family names. Many of the pedigrees contain minor additions in the hand of Thomas Talbot the younger.

MS. Dodsworth 2, 110 leaves: 'Liber Genealogiarum ... collectarum ... per Rogerum Dodsworthe', dated '20 Octo. 1635': Cf. fols. 50, 77v. At fol. 78 Dodsworth has added, Sept. 1637, his own pedigree and that of his wife, Holcroft Hesketh, and has entered, on fol. 58v, two Latin pedigrees of the Clavering family 'ex magno libro nigro Ricardi St. George militis'.

There are a few sketches of seals. Four leaves containing 'nomina separalium cartulariorum hoc opere [sc. Monastico Anglicano] citatorum' have been bound in after fol. 66.

MS. Dodsworth 3, 181 leaves:'Genealogiae ... extractae et compositae studio et industria Rogeri Dodsworthe Eboracensis, 1636.' Some of the North-Country pedigrees in this volume have been brought down by Dodsworth to his own time and dated, viz:

In addition to his own collections Dodsworth has utilized, on a few occasions, those of St. Loo Kniveton (fols. 15, 61, 62v) and of John Archer (fols. 85v, 90v). A spurious charter of king William i to Robert de Umfranvill occurs at fol. 151v. A cross at the top of many of the leaves indicates, as appears from a note on fol. iii, that the succeeding pedigree has been transcribed by Nathaniel Johnston of Pontefract into his collections.

Johnston has entered at fol. 122 an alphabetical index of some collection of north-country pedigrees, not Dodsworth's. Fols. 171-8 of the original foliation are wanting, and fol. 170 is misplaced after fol. 183.
