Bartemius Crouch Jr's mother

Mrs. Crouch (abt 1922 - 1982) was the wife of Bartemius "Barty" Crouch Sr. and mother of Barty Crouch, Jr.. She participated in one of the few escapes from Azkaban in the prison's history.

Early life
Nothing is known about Mrs. Crouch's early life, but she was a pure-blood witch, and she eventually married Barty Crouch Sr.. The couple had one son, named after the father, who was too focused on his career to care for his wife and son.

Aftermath of the First Wizarding War
Shortly after Lord Voldemort's first downfall, in 1981, Barty Jr. was caught amongst a group of Death Eaters who were convicted of torturing Aurors Alice and Frank Longbottom into insanity. Mrs. Crouch was present for her son's trial in Courtroom Ten, sitting next to her husband, who presided as the judge, sobbing. She suffered the terrible and sad experience of watching her husband renounce their 19-years old son and condemn him to life in Azkaban without listening to boy's crying pleas and explanations. After the sentence was passed, she collapsed in shock and grief of what had happened.

Rescuing her son and death
"My mother saved me. She knew she was dying. She persuaded my father to rescue me as a last favour to her."

- Barty Jr. describing his mother's last favour.

About one year after their son's imprisonment, Mrs. Crouch's health deteriorated dramatically from the stress. In the last few weeks of her life, Mrs. Crouch convinced her husband to allow her to trade places with her son in the wizard prison during their deathbed visit of their son that was permitted due to her husband's high status in the Ministry. Both mother and son drank Polyjuice Potion to take each other's appearance, and she went to Azkaban while Barty Jr. went to live in hiding with the help of their House-elf Winky. Mrs. Crouch died shortly thereafter in Azkaban, and was buried by the Dementors outside the walls under her son's name and appearance.

Since Barty Sr. couldn't have retrieved his wife's body from Azkaban without exposing what they had done, he held a quiet, private funeral for her, with an empty grave.

Physical appearance
Mrs. Crouch was a short, frail and wispy-looking witch. When she swapped places with her son in prison, she took on his appearance for the remainder of her life, and died bearing his form and name.

Personality and traits
Mrs. Crouch was a frail and emotional woman, as she was sobbing when her son was accused of crimes punishable by life sentence, to the point of fainting when her husband ruthlessly carried out the sentence and denouncing their son. She was a very loving mother, as she swapped places with her son to allow him to escape prison while suffering in his place and desiring him to live out his new life for the better. According to Winky, Mrs. Crouch would have wanted her son to enjoy some fresh air and freedom, not to be imprisoned by the Imperius Curse.

Husband
"He loved her as he had never loved me."

- Barty Jr. describing his father's love for Mrs. Crouch.

Mrs. Crouch's husband, Barty Crouch Sr., was very neglectful of his family life due to his devotion in the Ministry of Magic's eradication of the Dark Forces such as the Death Eaters. She was crushed when he dismissed their only son and sentenced him to Azkaban for life. However, they clearly loved each other deeply, no matter how the public views Mr. Crouch's ruthlessness, as he agreed to his wife's dying wish to save their son in exchange for the last few weeks of her terminally-ill life. As Barty could not retrieve his wife's corpse without fearing exposure of the jailbreak, he had to stage her death and hold a quiet, private funeral for her with an empty grave.

Son
"She said my mother would have wanted it. She told my father that my mother had died to give me freedom. She had not saved me for a life of imprisonment"

- Barty Jr. reiterating what Winky claimed Mrs. Crouch would have wanted.

Mrs. Crouch loved her only son, Barty Crouch Jr., very much. She was sobbing uncontrollably when he was convicted of a crime, and collapsed in shock and grief when her husband sentenced their child to life in prison. Mrs. Crouch's love made her sacrifice her own life to rescue her son, and hoped that he would be able to live a second chance of freedom and a new leaf. She died bearing his appearance and name.

Originally, Barty Jr. seemed to have loved his mother in return, as he was crying for her help during his sentencing, and was screaming for her for the first week in his cell. However, as time passed, with the combination of the Dementors' negative effects and his father's cruel and ruthless disinheriting, this caused Crouch Jr. to suffer a severe mental decline, changing him into an insane and psychopathic murderer who was fanatically loyal to Lord Voldemort, thus blinding him from those who truly loved him, namely his mother and the house-elf Winky. This renewed hatred led Barty to forget his mother and commit more crimes, such as patricide and reentering Voldemort's services, and then receiving the worse-than-death Dementor's Kiss. Conclusively, Mrs. Crouch's love, sacrifices and good intentions were tragically wasted.
