Teresa Gil was already widowed when the queen died in 1251, leaving the couple free to pursue their relationship openly and to enter a common law marriage not consecrated by the
Roman Catholic Church. In 1255, the king issued a charter granting Teresa Gil the tax-exempt castle of
Jérica, to be inherited by their descendants, male or female, after her death. The charters do not mention Teresa Gil as the king's wife; in fact, their form is the one used for concubinage contracts. Thus, historians have sometimes referred to her as the king's concubine, but James's letter to
Pope Clement IV in 1265 confirms that they were married. Nevertheless, she was never queen. The couple had their first son,
James, around 1255, and their second,
Peter, in c. 1259. == The king's great matter ==
