A series of pedigrees transcribed by William Webb, collected c. 1816-1853, 188 folios. The pedigrees were mainly supplied by the College of Arms. Nearly all are of members of Cambridge University, tracing their descent from Edward I or Edward III. There are also a few descending from Henry VII, and two examples descending from the kings of Scotland. The pedigree on fo. 37v is of Henry VIII's descent through Elizabeth de Clare, foundress of Clare Hall. Written from the other end of the book on fos 163-170 are copies of documents concerning the Worts Benefaction, 1715 and 1729. On fo. 188 is a copy of Thomas Martyn's patent of appointment as regius professor of botany, 1793. Fos 67-162 and 171-187 are blank.
