Being the daughter of King John of England, she owed her loyalties to her father due to the fact that he provided her a suitable title. Joan was born from an outcast mother who played mistress to King John, and was illegitimate. Her father being able to gain her the title of Princess of Wales was a feat that earned her respect and loyalty. At the beginning of her marriage with Llewelyn, she showed her first sign of spunk by burning her husband's bed after she walked in on him with his lover. At the time she was only 14, and didn't know that under Welsh law, she could have rightfully murdered the woman her husband was with... Llewelyn and King John became allies through the marriage of Joanna. While Llewelyn would assist King John on crusades and paid him homage, King John constantly betrayed their alliance by encouraging wars among the Marcher lords and stirring up trouble for Llewelyn. Knowing this, Joanna openly defied her father when her husband was forced to yet again pay homage to the king and pay him a ridiculous amount of money. When Llewelyn paid homage to the king, Joanna walked over to her husband, knelt, and swore fealty and loyalty to him. She ruled alongside her husband in Wales, created a scandal or two, but was still considered a powerful and loyal woman.
Saint Itta (also Ida, Itte, or Iduberga) (died May 8, 652) was the wife of Pepin of Landen, mayor of the palace of Austrasia. Her ancestry is uncertain, but she was probably from a noble, comital family in Aquitaine.
On the advice of the missionary bishop Saint Amand, bishop of Maastricht, after Pepin's death, she founded the Benedictine nunnery at Nivelles, with a monastery under the abbess. She herself entered it and installed as abbess her daughter Gertrude, perhaps after resigning the post herself.
She had by Pepin another daughter, Abbess Begga of Andenne. By Begga, she is the grandmother of Pepin of Heristal and one of the matriarchs of the great Carolingian family. Her only son was Grimoald, later mayor of the palace, and father of King Childebert the Adopted.
Both her daughters were later canonised, as was she. Her feast day is May 8.
