The sources for this period are rather sketchy and few in number. The Liber Historiae Francorum wass written by an unknown author who was close to the center of power in Neustria. The Continuations of the Chronicle of Fredegar consist of three parts: the first ten chapters are based on the Liber Historiae Francorum while the second part (chapters 11-33) covers the period until 751 was written for Count Childebrand, the brother of Charles Martel and then the next twenty chapters covering events down to 768 were written by Count Nibelung, the son of Childebrand. Arguments concerning the authorship of Fredegar Chronicle are numerous to the point of becoming a “cottage industry”. These sources are available in English translations as follows:

The Letters of Saint Boniface are also found in English translation in: Emerton, Ephraim, The Letters of Saint Boniface. New York: Columbia University of Records of Civilization, 1976; his Vita can be found in: Talbot, C. H., ed. The Anglo-Saxon Missionaries in Germany. New York: Sheed and Ward, 1954; along with those of Willibrord, Strum etc. His letters were extremely critical of conditions in the Frankish Church that he wanted to reform. Boniface probably darkened the picture in order to support his demands for reform.
