In the same year the King conceded to William de Ferrers that of 300 marks by which he made fine with him because he had married Sibilla his daughter to Francus de Bohun without his assent and licence that the render should be 20Li. annually until the sum was paid. In the same year both William de Ferrers, Earl of Derby, and Agnes, his countess, were deceased, and their lands taken into the King's hands and committed to custody, as we learn from an entry on the Fine Roll, dated at Westminster 25th September 1247 ; and on the 10th of November following the King took the homage of William de Ferrers of all the lands and tenements which had been those of Agnes, late Countess of Derby, of which the Castle of Chartley, com.
