William I Marshal, b. 1146 in Rockley, Marlborough, Wiltshire, England, d. 14 May 1219 in Caversham, Henley, Oxfordshire, England, buried aft. 14 May 1219 in Temple Church, London, Middlesex, England

Father: John "the Marshal" Fitzgilbert, b. ABT 1105 in Pembroke, Pembrokeshire, Wales, d. 1164 in Newbury Castle, Wiltshire, England
Mother: Sibilla (Sibyl) de Salisbury, b. ABT 1139 in Pembroke, Pembrokeshire, Wales, d. 3 June
William was knighted in 1167, and was travelling with his uncle Patrick, Earl of Salisbury, and Queen Eleanor near the castle Lusignan. The Lusignan brothers attacked and killed Patrick, who was unarmed. William was wounded and taken prisoner while defending the Queen's retreat into the castle, and trying to avenge his uncle's murder. He was ransomed by Queen Eleanor. William was appointed head of the military household in 1170. From then until the death of the young Prince Henry (whom William knighted in 1173) in 1183, William established his status as an undefeated knight of the tournaments. He fought in 500 matches and never lost. After Prince Henry's death, William took his cross to the Holy Land and joined the Crusades with King Guy of Jerusalem and the Templar Knights.

King Richard I gave William to wife Isabel de Clare. Upon this marriage William inherited all the lands which had been held by Richard Strongbow de Clare, Isabel's father, including Pembroke and Striguil, and the Lordship of Leinster in Ireland.

King John wrongly accused William of treason and began seizing his castles. William refused to fight John, as that would break his oath of fealty. When a bishop persuaded King John to expell his foreign advisors, John realised the error of his ways and restored William's lands to him. Upon John's death in 1216, William was chosen by his peers to act as Regent for young Henry III, who was nine years old. Henry was knighted and crowned under the seal of the Earl of Pembroke.

William served as Marshal of the Royal Household under four kings: Henry II, Richard I "the Lionheart", John Lackland, and Henry III.

It was said that William took two manors that the Bishop of Ferns could not get back. Some years after William's death the Bishop placed a curse on William's family that none of his sons would have children. Each of William's sons became Earl of Pembroke and Marshall of England, but all died without issue.

In one of her essays on William Marshal, Catherine Armstrong says," William might have inherited some of the physical strength and knowledge of military strategy from his father, but as a second son, he would become in his own right and by his own abilities, skills, and sense of honor the best of chivalric knighthood, a "familiaris Regis," the Earl of Pembroke, and the Regent of England."

John was also known as John Mareschal. He was the Marshall of the Royal Household and later took the hereditary title as his name. There is some disagreement about John's mother. He is said to be a descendant of Miles de Venoix, which is only possible if his mother is Mary de Venoix instead of de Venus. It is possible, though, that Mary de Venois and Ms. de Venus are the same person.

During the civil war between Empress Matilda and her cousin Stephen, John at first supported Stephen, though some historians claim he didn't much care who won. He later chose to support Empress Matilda, and was with her at the siege of Winchester. It was decided that the Empress should retreat to John's castle of Ludgershall with him while Robert of Gloucester continued the battle. At Wherwell John sent the Empress ahead to his castle with Brian Fitzcount, while he defended her retreat with a few of his knights at the River Test. Only John and one of his knights survived the battle here, and they retreated to Wherwell Abbey. The enemy followed them there and set fire to the abbey, then left thinking John had been killed. He survived and made his way to his castle of Marlborough, losing one eye from iron that melted in the fire.

John was daring, ruthless, and had more than his share of daring, energy, and ambition. He was known for his ability as a soldier and knight, his cunning, and his love of military stratagems. The "Gesta Stephani" describes him as "a limb of hell and the root of all evil."

Later John gave his son William to Stephen as a hostage as part of a treaty. At the siege of Newbury in 1152, after John broke the treaty by attacking the lands of Stephen's supporters, Stephen reminded him of the son he had given as hostage, whom he now had the right to execute. John's famous reply was that he, "had the anvils and the hammer to forge still better sons." Stephen did not kill William, but rather sent him to Normandy to train as a knight.

One of John's most frequent victims was Patrick, Earl of Salisbury. After several years of attacking each other, both had enough. They worked out a compromise in 1141 in which Patrick would switch to Matilda's side, and John would put aside his wife and marry Patrick's sister, Sibyl.

John and Sibyl had two more sons and two daughters than what is listed here.
