Elisabeth endured imprisonment, abuse, and inbreeding in the basement of her home, leading to the birth of seven children. The details of her abduction, the harrowing ordeal, and her return to society are documented in various articles. However, information about other members of Elisabeth’s family, including her mother and siblings, remains scarce.

To delve deeper into her siblings, six of them are from her parents’ marriage, and this article focuses on those siblings and their activities.

Starting with Elisabeth’s siblings from her parents’ marriage, she has six siblings from her parents’ union. They are Ulrike Fritzl, Rosemarie Fritzl Jnr., Harald Fritzl, Gabrielle Fritzl, Josef Fritzl Jnr., and Doris Fritzl.

  • Ulrike Fritzl, the oldest sibling, born in 1957, became an educator, currently residing in Terrible Goisern at the foot of the Alps. She is married and maintains a chalet-style country property.
  • Rosemarie Fritzl Jnr., born around 1960, is the second daughter of Josef and Rosemarie Fritzl. Specific details about her life are not extensively available.

Rosemarie Jnr. was named after her mother, also known as Rosemarie. While the specific nature of her relationship with Elisabeth during their upbringing is not explicitly clear, one would assume it was similar to any ordinary sibling relationship.

Before the Fritzl case in 2008, not much was known about the Fritzl family, including their educational backgrounds. It can be presumed that Rosemarie Jnr. had some level of formal education, but without specific details, it is impossible to determine the extent of her academic achievements.

As an adult, Rosemarie Jnr. reportedly lived in Linz years ago, just 35 miles from Elisabeth’s ordeal. She was said to have regularly visited Elisabeth and her children in the months and weeks following their liberation from their father’s clutches.

Currently, not much is known about Rosemarie Fritzl Jr., including her current circumstances and whether she has a family and children like her sisters Ulrike and Elisabeth. Harald Fritzl is the first son of Josef and Rosemarie Fritzl and Elisabeth’s immediate older brother.

Born in 1963, in Amstetten, Austria, Harald Fritzl was raised by his parents. During his father’s trial, Elisabeth’s older brother testified that he and his siblings had been raised under the harmful influence of their father, disclosing that he had been physically assaulted by Josef Fritzl on several occasions.

His statement contradicted his father’s lawyer, who claimed Josef Fritzl was not a monster. While the nature of his relationship with Elisabeth before her disappearance is not fully known, he was supportive of Elisabeth and her children after their liberation.

His academic qualifications and career path are not publicly known. He reportedly left home to get married, preferring a life away from the spotlight. His current whereabouts are unknown, but he likely resides in or around Austria, like most members of his birth family.

Gabrielle Fritzl, born in 1971, is the fifth child of Josef and Rosemarie Fritzl and Elisabeth’s younger sister. Growing up with Elisabeth in the same house, she was 13 when Elisabeth disappeared. For the next 24 years, she believed Elisabeth had joined a secret organization and left her children for their parents to care for.

Certain reports suggest she harbored some resentment towards her sister, wondering what kind of mother would leave her children. These feelings turned to anger towards her father when the truth of his actions was revealed.

Gabrielle Fritzl likely received formal education, but details are unclear. Her current means of living remain undisclosed. Reportedly, she lives with her husband, Juergen Steerage, in a chalet-style house near Amstetten. They have a child together, and there is a sign outside their home in Austrian that reads “Journalists not wanted,” likely to deter intrusive reporters.

Named after his father, Josef Fritzl Jnr. is Gabrielle Fritzl’s twin brother, born in 1971. Elisabeth Fritzl’s younger brother coexisted with her until their father convinced them she had joined a secret organization. He was naturally distressed about the situation, especially when he had to share a space with Elisabeth’s supposedly abandoned children.

Like Gabrielle, he felt terrible for Elisabeth when he learned of their father’s actions. Details about Josef Jnr.’s formal education are insufficient, and as of Elisabeth’s liberation, he reportedly still lived with his parents in Ybbsstrasse, Amstetten. Choosing to lead a life away from the spotlight means his current whereabouts are unknown.

Doris Fritzl, like her older siblings, was born in Amstetten, Austria, in 1972. She is the youngest child of Josef and Rosemarie Fritzl and also Elisabeth Fritzl’s youngest sibling from her parents. Elisabeth was around six years old when Doris was born, meaning they had few interactions as siblings.

Raised by her parents, Doris lived at home and was only 12 years old when her sister Elisabeth became a prisoner due to their wicked father.

Doris was a fully grown 36-year-old woman when Elisabeth reintegrated into society 24 years after disappearing just after her eighteenth birthday.

Like her other siblings, Doris prefers to keep her affairs private and has not provided much information to the media regarding her academic qualifications. Doris Fritzl is happily married, and following revelations about her family, she chose to be addressed by her married name Heniki. Not much is known about her current whereabouts.

Elisabeth Fritzl Had Seven Other Siblings, Her Children with Her Father Before the events of 2008, Elisabeth’s father’s neighbors believed he was a nice father of seven with no secrets. They were utterly shocked when it was revealed that he had fathered seven other children with his daughter Elisabeth after kidnapping and tormenting her for years. His double life remains a stunning revelation to his neighbors, who had respected him.

Due to what happened in what is now named the “Inbreeding Basement,” Elisabeth Fritzl had seven other siblings.

A sinister twist of fate also means that she was burdened with the unwanted duty of giving birth to those siblings. Let’s meet Elisabeth Fritzl’s other siblings.

Kerstin Fritzl was born in captivity on August 30, 1988, in Amstetten, Austria. She has a twisted relationship with the malevolent and imprisoned serial attacker, Josef Fritzl, as he is not only her father but also her grandfather due to the fact that she was conceived after her father/grandfather assaulted her mother/sister.

Kerstin spent the first 19 years of her life in the inbreeding basement. She only glimpsed what the rest of the world was like when Josef had to take her to the hospital after she fell ill with an infection. Doctors were shocked that someone so young was so severely malnourished and missing around 50% of her dentition.

Now 34 years old, Kerstin Fritzl did not attend school for most of her life, and her current whereabouts are unknown since she survived the inbreeding basement.

Almost two years after the birth of Kerstin, Elisabeth gave birth to her second child and eighth sibling on February 1, 1990. This time it was a boy named Stefan. Stefan was also raised in the inbreeding basement alongside Kerstin and another sibling. Like Kerstin, he attended no school for the first 17 years of his life.

Reports also suggest that at 5 feet 7 inches, Stefan likely walks with a slight slant due to having lived too long in a basement that only measured 5 feet 6 inches. Stefan lives in a two-story family home with all his siblings. The house is under the constant watch of security guards and CCTV cameras.

Lisa Fritzl was born on August 29, 1992, in Amstetten, Austria. She is often referred to as one of the upper children since she was one of the three children, including Monika (born February 26, 1994), and Alexander (born April 28, 1996), who were raised in the main house by Elisabeth’s parents, Josef and Rosemarie.

She had a normal life, including attending a school where she was described as fun and bubbly. She also lives with her mother and five surviving siblings in the two-story building located in a small village in the Austrian countryside. The second of the upper children, Monika Fritzl, was born on February 26, 1994, in Amstetten, Austria.

She was also raised by her grandmother Rosemarie Fritzl after her father/grandfather had convinced his wife that their mother, Elisabeth, had abandoned them on the doorstep of their home.

Her upbringing essentially followed the same trajectory as Lisa’s as she similarly led a normal life, including attending school. She has since been reunited with her mother/sister, Elisabeth, and currently lives in the same two-story building with her basement relatives.

The last of the three children who were raised upper by Josef and Rosemarie Fritzl, Elisabeth’s parents, Alexander Fritzl, was born on April 28, 1996, along with his twin brother Michael. Alexander also had the privilege of living a fairly normal life that ultimately changed when the world learned of his father’s/grandfather’s wickedness.

He was also fortunate to have lived long enough to witness the rescue of his mother/sister from the inbreeding basement. His twin brother Michael was not as fortunate.

He is also one of the six surviving children who live in the Austrian villa with their mother/sister.

Michael Fritzl is Alexander’s twin brother and was born on April 28, 1996. Unfortunately, he died on May 1, 1996, just 3 days after his birth. His cause of death was believed to be linked to the complications he developed due to his inbreeding-related birth. His body was disposed of in the furnace that kept the basement warm.

Felix Fritzl is the youngest of Elisabeth Fritzl’s children/siblings. He was born on December 16, 2002, and still feels the effects of living the first six years of his life in the inbreeding basement. That’s what some reports revealed although he could walk when they were liberated from bondage, Felix had preferred to crawl and had clung tightly to his mother for extended periods. He is also one of the residents of the two-story building that never closes its doors.
