While inwardly considering how endlessly and with how many honours of parental and sincere affection of our aforementioned uncle and of his mature counsel we are on all sides blessed, we have judged it appropriate and worthy that in consideration of his merits, and in contemplation of the grace of persons, we should endow you, who are resplendent with probity and virtuous life and conduct, and are born of royal stock and divinely marked with many virtues and gifts, with the protection of grace and favour by special prerogative. Thus it is that, yielding to the prayers of our said uncle, your father, we grant to you who, so it is claimed, have suffered such defect of birth, that, notwithstanding this defect, which, together with its various consequences, we wish to be fully included in these presents, you may nevertheless receive all honours, dignities, preferments, estates, degrees, and public and private offices, both perpetual and temporal, and feudal and noble rights, by whatsoever name they are called, such as duchies, lordships, earldoms, baronies, or whatsoever other fiefs they be, whether they be dependent upon or held of us mediately or intermediately, which may be preferred, promoted, elected, taken up and allowed, and received, retained, performed and exercised prudently, freely and lawfully, as if you were born in wedlock, notwithstanding any statutes or customs of our kingdom of England decreed or observed to the contrary; and we dispense you [from this defect] by the tenor of these presents, by the plenitude of our royal power and with the assent of our parliament; and we restore you and each of you to legitimacy.
The History of William Marshal was commissioned by his son shortly after William’s death in 1219 to celebrate the Marshal’s remarkable life; it is an authentic, contemporary voice. The manuscript was discovered in 1861 by French historian Paul Meyer. Meyer published the manuscript in its original Anglo-French in 1891 in two books. This book is a line by line translation of the first of Meyer’s books; lines 1-10152. Book 1 of the History begins in 1139 and ends in 1194. It describes the events of the Anarchy, the role of William’s father John, John’s marriages, William’s childhood, his role as a hostage at the siege of Newbury, his injury and imprisonment in Poitou where he met Eleanor of Aquitaine and his life as a knight errant. It continues with the accusation against him of an improper relationship with Margaret, wife of Henry the Young King, his exile, and return, the death of Henry the Young King, the rebellion of Richard, the future King Richard I, war with France, the death of King Henry II, and the capture of King Richard, and the rebellion of John, the future King John. It ends with the release of King Richard and the death of John Marshal.

The Deeds of the Dukes of Normandy
The Gesta Normannorum Ducum [The Deeds of the Dukes of Normandy] is a landmark medieval chronicle tracing the rise and fall of the Norman dynasty from its early roots through the pivotal events surrounding the Norman Conquest of England. Originally penned in Latin by the monk William of Jumièges shortly before 1060 and later expanded at the behest of William the Conqueror, the work chronicles the deeds, politics, battles, and leadership of the Norman dukes, especially William’s own claim to the English throne. The narrative combines earlier historical sources with firsthand information and oral testimony to present an authoritative account of Normandy’s transformation from a Viking settlement into one of medieval Europe’s most powerful realms. William’s history emphasizes the legitimacy, military prowess, and governance of the Norman line, framing their expansion, including the conquest of England, as both divinely sanctioned and noble in purpose. Later chroniclers such as Orderic Vitalis and Robert of Torigni continued the history, extending the coverage into the 12th century, providing broader context on ducal rule and its impact. Today this classic work remains a foundational source for understanding Norman identity, medieval statesmanship, and the historical forces that reshaped England and Western Europe between 800AD and 1100AD.
