He was Count of Ponthieu, ruler of a small province in northern France. It was one of six feudal counties that eventually merged to become part of the Province of Picardy, in northern France. Its chief town is Abbeville.

He was son and heir of John (Jean) I, Count of Ponthieu (died 1191) by his third wife Beatrice de St Pol. His father was the son of Guy II, Count of Ponthieu (who died on the Second Crusade 1147) and grandson of William III of Ponthieu, also frequently called William III Talvas, and who represented the senior line of the lords of Montgomery, once trusted vassals and allies of William the Conqueror.

Talvas was married on August 20, 1195 to Alys, Countess of the Vexin, the daughter of King Louis VII of France. She was some eighteen years older than he, and was said by some to have been seduced by King Henry II of England while betrothed to his son, King Richard the Lionheart. Richard sent her back to her brother, King Philip II of France, refusing to marry his father's mistress.

Philip then arranged for Alys to marry William Talvas, with the intent that the couple would be childless, and he would thus gain control of Ponthieu, a small but strategically important county. However, Alys then gave birth to a daughter and heiress, Marie, in 1199. This daughter was the maternal grandmother of Eleanor of Castile, first wife of Edward I, King of England, to whom Ponthieu and the disputed Vexin inheritance would eventually pass as Eleanor's dowry. William Talvas died in 1221, his daughter Marie being his heiress.

William was an important army commander in the Anglo-French War (1202-1214). He also participated in the Albigensian Crusade, particularly in the Siege of Termes in 1210.
He led the left wing of the victorious French army in the Battle of Bouvines in 1214.

https://en.wikipedia.org/wiki/Joan,_Countess_of_Ponthieu

She was Queen consort of Castile and León, Countess of Ponthieu, and Countess of Aumale.

Joan was the eldest daughter of Simon of Dammartin, Count of Ponthieu (1180-21 September 1239) and his wife Marie of Ponthieu, Countess of Montreuil (17 April 1199-1251). Her paternal grandparents were Alberic II, Count de Dammartin and Mahaut de Clermont, daughter of Renaud de Clermont, Count of Clermont-en-Beauvaisis, and Clémence de Bar. Her maternal grandparents were William IV of Ponthieu and Alys, Countess of the Vexin, daughter of Louis VII of France and Constance of Castile.

After secret negotiations were undertaken in 1234, it was agreed that Joan would marry King Henry III of England. This marriage would have been politically unacceptable to the French, however, since Joan stood to inherit not only her mother's county of Ponthieu but also the county of Aumale that was vested in her father's family. Ponthieu bordered on the duchy of Normandy, and Aumale lay within Normandy itself. The French king Philip Augustus had seized Normandy from King John of England as recently as 1205, and Philip's heirs could not risk the English monarchy recovering any land in that area, since it might allow the Plantagenets to re-establish control in Normandy.

As it happened, Joan's father Simon had become involved in a conspiracy of northern French noblemen against Philip Augustus and to win pardon from Philip's son Louis VIII, Simon, who had only daughters, was compelled to promise that he would marry off neither of his two eldest daughters without the permission of the king of France.

In 1235, the queen-regent of France, Blanche of Castile, invoked that promise on behalf of her son, King Louis IX of France, and threatened to deprive Simon of all his lands if Joan married Henry III. Blanche also petitioned the Pope to deny the marriage based on consanguinity. He agreed, denying the dispensation which Henry had sought and paid for. Henry therefore abandoned the project for his marriage to Joan and in January 1236 married instead Eleanor of Provence, the sister of Louis IX's wife.

In November 1235, Blanche of Castile's nephew, King Ferdinand III of Castile, lost his wife, Elisabeth of Hohenstaufen, and Blanche's sister Berengaria of Castile, Ferdinand's mother, was concerned that her widowed son might involve himself in liaisons that were unsuited to his dignity as king. Berengaria determined to find Ferdinand another wife, and her sister Blanche suggested Joan of Dammartin, whose marriage to the king of Castile would keep her inheritance from falling into hostile hands. In October 1237, at the age of about seventeen, Joan and Ferdinand were married in Burgos. Since Ferdinand already had seven sons from his first marriage to Elisabeth of Hohenstaufen, there was little chance of Ponthieu being absorbed by Castile.

They had four sons and one daughter:

1. Ferdinand (1239-ca 1265), Count of Aumale, who married after 1256 Laure de Montfort, Lady of Espernon, and had issue.
2. Eleanor (1240-1290), Countess of Ponthieu, who married king Edward I of England and had issue.
3. Louis (1243-ca 1275), who married Juana de Manzanedo, Lady of Gaton, and had issue.
4. Simon (1244), died young and buried in a monastery in Toledo.
5. John (1246), died young and buried at the cathedral in Córdoba.

After Ferdinand III died in 1252, Joan did not enjoy a cordial relationship with his heir, her stepson Alfonso X of Castile, with whom she quarreled over the lands and income she should have received as dowager queen of Castile. Sometime in 1253, she became the ally and supporter of another of her stepsons, Henry of Castile, who also felt Alfonso had not allowed him all the wealth their father had meant him to have. Joan unwisely attended secret meetings with Henry and his supporters, and it was rumored that she and Henry were lovers. This further strained her relations with Alfonso and in 1254, shortly before her daughter Eleanor was to marry Edward of England, Joan and her eldest son Ferdinand left Castile and returned to her native Ponthieu.

Upon her mother's death in 1251, Joan succeeded as Countess of Ponthieu and Montreuil, which she held in her own right. Sometime between May 1260 and 9 February 1261, Joan took a second husband, Jean de Nesle, Seigneur de Falvy et de La Hérelle (died 2 February 1292).

During her marriage to Jean de Nesle, Joan ran up considerable debts and also appears to have allowed her rights as countess in Ponthieu to weaken. The death of her son Ferdinand in 1265 made her next son, Louis, her heir in Ponthieu but around 1275 he, too, died, leaving two children. But according to inheritance customs in Picardy, where Ponthieu lay, Joan's young grandson John of Ponthieu could not succeed her there; her heir in Ponthieu automatically became her adult daughter Eleanor, who was married to Edward I of England.

It does not appear that Joan was displeased at the prospect of having Ponthieu pass under English domination; from 1274 to 1278, in fact, she had her granddaughter Joan of Acre (the daughter of Edward I and Eleanor) with her in Ponthieu, and appears to have treated the girl so indulgently that when she was returned to England her parents found that she was thoroughly spoiled.

That same indulgent nature appears to have made Joan inattentive to her duties as countess. When she died at Abbeville, in March 1279, her daughter and son-in-law were thus confronted with Joan's vast debts, and to prevent the king of France from involving himself in the county's affairs, they had to pay the debts quickly by taking out loans from citizens in Ponthieu and from wealthy abbeys in France.

They also had to deal with a lengthy legal struggle with Eleanor's nephew, John of Ponthieu, to whom Joan bequeathed a great deal of land in Ponthieu as well as important legal rights connected with those estates. The dispute was resolved when John of Ponthieu was recognized as Joan's successor in Aumale according to the inheritance customs that prevailed in Normandy, while Edward and Eleanor retained Ponthieu, and John gave up all his claims there. By using English wealth, Edward and Eleanor restored stability to the administration and the finances of Ponthieu, and added considerably to the estate by purchasing large amounts of land there.
