Lineage from William Marshal
Our medieval grandfather, William Marshal was a 13th-century knight, distinguished in battle, a Magna Carta baron and devoted servant of the crown of medieval England. William Marshal was one of history’s most remarkable knights, serving four kings with such loyalty that his position of trust eventually placed him in the highest office of the land, Regent of England. His history reads like a novel. In marriage he was matched with a bride of equal prestige, Isabel, daughter of Richard Fitz Gilbert de Clare, Earl of Pembroke. With her came wealth, land and titles.
