A transcript, with additions, by Sir Edward Walker, herald and secretary at war, of 'Morganiae Archaiographia' or 'A Booke of the Antiquityes of Glamorganshire ... 1578' by Rice Merrick (Rhys Amheurug) of Cottrell, St. Nicholas, Glamorgan. The work was privately printed by Sir Thomas Phillipps, Middle Hill, in 1825, and reproduced, with notes by James Andrew Corbett, in 1887. The transcriber's additions, completed on 3 April 1675, consist largely of 'A Briefe History of the Originall Descent of ye most Noble Famly of ye Grandvilles, or de Grana Villa, vulgarly called Grenviles, or Greenfeilds, descended from ye Dukes of Normandy, faithfully collected out of seuerall ancient writings in the Tower, & elsewhere. Anno D'ni. 1639', illustrated with one hundred and one coats-of-arms painted in colour.
