We've heard about the strained relationship between Michael Jackson and his father, which affected Michael's life until the very end. The immediate family members of many famous people played a significant role in their lives, influencing them in various ways and shaping their personalities. We know little about their families because some prefer to remain in the shadows. Did you know that Peter Pan in J.M. Barrie's books never grew up because his brother died before he was 14, and in his mother's eyes, he was forever a boy?
1. John, Robert, and Ted Kennedy had a sister named Rosemary. She often indulged in rebellious behavior, such as sneaking out of the house at night, and frequently had outbursts of anger. Her father feared she would bring shame on the family, so at 23, he attempted a lobotomy on her, but the operation failed, leaving her permanently incapacitated.

Rose Marie "Rosemary" Kennedy was born "different" into a prominent family. From childhood, she lagged behind her siblings and had behavioral problems. Not wanting to embarrass her, her parents kept her out of the public eye, but as she grew older, she could no longer remain in the shadows. She began to rebel and suffered from severe mood swings.
She would sneak out at night from the Washington, D.C., convent school where she attended, irritating her parents, who wanted all their children to behave appropriately. Some observers believed Rosemary behaved this way because of the constant pressure to live up to the high standards set by her siblings.
Joseph Kennedy, fearing that his daughter would harm his political career, asked doctors to perform a lobotomy on his daughter in November 1941, when Rosemary was 23. His wife knew nothing about it. The lobotomy failed. Afterward, Rosemary acted like a two-year-old, could no longer walk, could not speak properly, and lost bladder control. She was subsequently institutionalized.
Her father later built a house for her, where she was cared for by two Catholic nuns, along with two other people who visited her occasionally. Her mother, Rose, didn't visit her for 20 years. The family constantly told everyone she was "mentally retarded" and hid the fact that she had undergone a lobotomy. On January 7, 2005, Rosemary died of natural causes, with her surviving siblings by her side. (source)

3. Maria Anna Mozart was Mozart's older sister and an accomplished musician, considered one of the best in Europe. After she reached marriageable age, her parents no longer allowed her to showcase her talents.

Nannerl, whose real name was Maria Anna Walburga Ignatia Mozart, was a musical genius, like her younger brother, Wolfgang Amadeus Mozart. At the age of seven, she learned to play the harpsichord from her father, Leopold. She made several concert tours to Paris and Vienna with her brother and father, and was greeted with applause everywhere. Her talents rivaled those of her brother, and she was known not only as an excellent harpsichordist but also as a good pianist. Sometimes her name appeared in the concert credits (at the top of the list of performers).
If Nannerl's parents hadn't forbidden her from attending concerts when she turned 18, she would have made an even more illustrious name for herself in history. Due to 18th-century social attitudes, Nannerl was forced to remain at home after reaching marriageable age. In his letters, Wolfgang repeatedly praised the musical works she composed.
Nannerl was an obedient child, did not go against her father's will, and despite falling in love with a captain and private tutor named Franz Lippold, at the age of 32 she married a widower, a justice of the peace, at her father's request in 1783. She spent 14 years at home. (source)
