This is the revised edition of the first book ever to document the complete known genealogy of John of Gaunt, son of King Edward III and Queen Philippa. Since this is the usual lineage through which a commoner can enter the domain of European royalty, anyone who can connect his lineage to that of John of Gaunt can now be shown to share the same basic royal heritage as the most noble knight--the complete heritage, not just the Plantagenet ascent. Intended for the general reader as well as the specialist, this work draws together the massive labors of about 600 prominent genealogists and historians. Genealogists interested in royal and noble ancestry should search this exhaustively researched work for many new and interesting names to add to their pedigree charts.
