Joanna was born in to a cadet branch of House Lannister. She had at least one sibling, Stafford. Later she married her cousin Tywin. Joanna was not significantly older than Tywin.On their wedding day Tywin smiled, a very rare occurrence. Their marriage was a very happy one; Joanna became Tywin's trusted counselor and companion. Her influence on her husband was such that people would say Tywin ruled the Seven Kingdoms as Hand of the King "but was ruled at home by his lady wife."
While Joanna and Tywin were still betrothed, Joanna's brother Stafford Lannister was captured by Lady Tarbeck together with two other Lannisters, in response to Lord Tytos imprisoning Lord Tarbeck.
Her servant once caught Jaime and Cersei as children in flagrante delicto. When Joanna learned of this, she sent the maid away, moved Jaime's chamber to the other side of the castle, and put a guard outside of Cersei's chamber. Joanna then warned her twins that they must never do such a thing again, or else she would be forced to tell their father. Joanna died birthing Tyrion not long after this event. 
Joanna was a friend of the then-ruling Princess of Dorne, whom she knew from her time at court when they were companions to Princess Rhaella Targaryen. Her friend had two children, Oberyn and Elia Martell, who were not yet promised in marriage, so they planned to have their children wed each other. Before this could happen, Joanna died giving birth to her third child, Tyrion, and the marriages did not take place.
Recollections about Joanna
Tywin seldom spoke of his wife but was much saddened by her death. He never remarried. According to his brother, Gerion Lannister, "the best part of Tywin died with her." Another brother, Kevan, later took over Joanna's role as Tywin's most trusted counselor.
According to Ser Barristan Selmy, King Aerys II lusted for Joanna Lannister, something that caused further friction between the King and his Hand. At the wedding of Tywin to Joanna, Aerys drunkenly japed about how it was a pity the first night tradition was banned, and he took certain liberties in the bedding ritual when the men at the feast had to disrobe the bride.
|“||“Not loved. Mayhaps wanted is a better word, but ... it was only kitchen gossip, the whispers of washerwomen and stableboys ..."||”|
Ser Barristan, choosing his words with care, goes on to tell Dany of her father's behaviour during the wedding feast of Tywin and Joanna and during the bedding.
During the Siege of Riverrun Jaime dreams and sees a woman he barely recognizes. At first, he believes her to be Cersei. She asks if he will forget his father like he has forgotten her. She talks about the future Tywin wanted for his children: his son a knight and his daughter a queen. She cries when Jaime replies that they have indeed become that.
