After Amicia’s brother, Robert de Beaumont, died in 1204, his title of Earl of Leicester passed to Amicia and Simon’s son, also named Simon. However, the younger Simon lost the earldom in 1215 when King John granted it to Ranulf de Blondeville, Earl of Chester. The younger Simon had two sons – Amaury and yet another Simon. This last Simon (Amicia’s grandson) would later convince Ranulf to cede the earldom to him in 1238, though his later rebellion against the king in the Second Baron’s War would result in the return of the title to the crown from 1265 until 1267.
