London Bierk is the son of Canadian rock singer Sebastian Bach, best known as the former lead vocalist of Skid Row, and his former wife, Maria Aquinar. Although his father’s music career has attracted attention for decades, London has maintained a comparatively limited public profile.
As one of Sebastian Bach’s three children, London is frequently mentioned alongside his older brother Paris and younger sister Sebastiana. His family connections are well documented, but published accounts disagree about his exact age, and little authoritative information describes his professional or personal life.
London Bierk is the second son of rock musician Sebastian Bach and his former wife, Maria Aquinar. He has an older brother, Paris Bierk, and a younger sister, Sebastiana Bierk. Unlike Paris, who performs with their father, London has received limited media attention, and reports about his birth date conflict.

Who Is London Bierk?
London Bierk is best known through his connection to Sebastian Bach, whose powerful vocals helped establish Skid Row as one of the recognizable hard rock acts of the late 1980s and early 1990s. London is the middle child of Bach and Maria Aquinar, placing him between Paris and Sebastiana in the family.
His identity is supported by contemporary reporting rather than simply by online celebrity biographies. When Bach publicly announced his separation from Maria in December 2010, music publications identified the couple’s three children by name. London was specifically described as one of their two sons.
Unlike his father, London has not established a comparable public presence through widely documented performances, interviews, or entertainment projects. This distinction matters because articles about celebrity families sometimes treat a famous parent’s career as evidence of the children’s own interests or accomplishments.
London’s connection to the music industry is therefore best understood as a family relationship, not as proof that he has pursued professional music himself. His father’s public history provides useful background, but it should not be mistaken for London’s individual biography.

London Bierk’s Age and Birth Date
London Bierk’s age is one of the most frequently discussed details in online biographies, partly because published information is inconsistent. IMDb’s biographical trivia for Sebastian Bach identifies his second son as London Siddhartha Halford Bach and lists January 17, 1994, as his birthday.
However, a January 2011 report published by TV Guide described London as 14 years old when his parents’ separation became public. Billboard also reported that age in its contemporary coverage. Someone born in January 1994 would have been nearly 17 at that time, so the accounts cannot both be accurate.
The discrepancy makes it difficult to establish his precise age in 2026 without stronger firsthand evidence. While many newer biographies repeat the 1994 date, repetition alone does not resolve the disagreement between the older reporting and the entertainment database.
What is clear is that London was born during the years when his father was a major figure in hard rock. A precise birthday or present-day age should be treated cautiously unless more authoritative documentation becomes available.
London Bierk’s Parents: Sebastian Bach and Maria Aquinar
Sebastian Bach: His Famous Father
Sebastian Bach was born Sebastian Philip Bierk on April 3, 1968, in Freeport, the Bahamas. He grew up in Canada and eventually became internationally recognized as Skid Row’s lead singer. His time with the group produced well-known songs including “18 and Life,” “I Remember You,” and “Youth Gone Wild.”
After leaving Skid Row in the 1990s, Bach continued recording and performing as a solo artist. He also expanded into musical theater and television, appearing in productions such as Jekyll & Hyde and the series Gilmore Girls. His career has remained active through subsequent albums and concert tours.
In September 2025, a SPIN interview with Sebastian Bach examined his recording career, theater work, family connections, and lifelong enthusiasm for music. The profile also explored his appreciation for artwork created by his father, David Bierk.
London therefore belongs to a family with documented connections to both music and visual art. However, this artistic background does not establish whether he has pursued similar interests professionally.
Maria Aquinar: London’s Mother
Maria Aquinar, also known publicly as Maria Bierk, was Sebastian Bach’s first wife. The couple began their relationship before Bach achieved international fame and married in 1992. They subsequently raised three children together.
Maria occasionally appeared in entertainment programming connected with her husband’s career. One example was VH1’s I Married Sebastian Bach, which aired in 2004 and presented aspects of the couple’s life during Bach’s established music career.
On December 31, 2010, Bach publicly announced that he and Maria had separated. A contemporary report on their separation reproduced his statement explaining that they had effectively been living separately since April of that year.
The announcement identified Paris, London, and Sebastiana as their children. Although the marriage ended, their shared parenthood remains the central documented connection between London and both sides of his family.
London Bierk’s Siblings: Paris and Sebastiana
London has two siblings who are also children of Sebastian Bach and Maria Aquinar. Their different levels of public visibility help explain why readers sometimes encounter more information about Paris than London.
Paris Bierk: The Older Brother
Paris Bierk is London’s older brother and a professional drummer. His involvement in music has made him more visible in entertainment coverage, especially since he began performing alongside his father.
In February 2026, Parade reported on Sebastian Bach touring with Paris. Bach discussed how sharing a touring schedule with his son provided opportunities for ordinary family activities, including meals and travel between performances.
The singer also reflected on the difficulty of balancing family life with the demanding schedule of a professional musician. His comments provide firsthand insight into his experience as a father, although they specifically concern his working relationship with Paris rather than London’s individual circumstances.
Paris’s professional achievements should not automatically be attributed to London. Despite their shared surname and family background, established reporting documents Paris’s musical work far more extensively.
Sebastiana Bierk: The Younger Sister
Sebastiana Bierk is London’s younger sister and the youngest child of Sebastian Bach and Maria Aquinar. She was described as three years old in coverage published around the beginning of 2011.
Her name occasionally appears in articles and interviews about Sebastian’s family life, although she has not developed the same widely documented music career as Paris.
Some internet searches use phrases such as “daughter London Bierk” or “Bach daughter London Bierk.” These descriptions confuse the siblings. London is Sebastian Bach’s son, while Sebastiana is his daughter.
Why Does London Use the Bierk Name?
The difference between the surnames Bach and Bierk can create confusion when researching the family. Sebastian Bach was born Sebastian Philip Bierk, and Bach is the professional name associated with his music and entertainment career.
Consequently, family members may be identified using either Bach or Bierk in different publications. Paris, for example, is commonly called Paris Bach in coverage of his father’s touring band, while other reports use Paris Bierk.
The same variation helps explain why some biographical databases identify London with an expanded name ending in Bach, while most searches refer to him as London Bierk. These different forms should not be treated as evidence of separate individuals.
Readers researching Sebastian Bach’s children are therefore likely to encounter a mixture of stage-name and family-surname references.
What Is Known About London Bierk’s Career?
Unlike Paris, London has no consistently documented professional role in his father’s touring band or other major entertainment projects. Some online biographies describe him as a graphic designer, marketing professional, writer, or occasional musician, but these claims have not been reliably established through authoritative interviews or professional reporting.
There is also insufficient dependable evidence to identify a particular college, employer, recording project, or creative portfolio as his. Such details should not be presented as settled biographical facts merely because they appear repeatedly on celebrity-profile websites.
This does not establish that London has never worked in music, design, or another creative field. It means that the available reliable public record is too limited to provide a detailed professional history.
The distinction becomes especially relevant when comparing the brothers. Paris’s performances are independently documented by concert coverage and statements from Sebastian himself, whereas equivalent public evidence about London’s career is much harder to establish.
London Bierk Photos, Instagram, and Public Appearances
Searches for London Bierk photos often return pictures of Sebastian Bach, Paris Bierk, or other members of the extended family. Because several articles reuse family photographs without clear identification, images should be checked against their original captions before being attributed to London.
There is likewise no sufficiently established public Instagram account that can confidently be presented as London’s official profile. A matching name or a photograph featuring someone connected to Sebastian Bach is not enough to authenticate an account.
London also receives relatively little independent coverage in major entertainment publications. His public appearances and recent activities are not documented with the same frequency as those of his father and older brother.
That limited reporting should not be interpreted as proof that London has deliberately withdrawn from public life. It simply means there is less dependable information about him than about relatives who regularly participate in professional entertainment.
London Bierk’s Latest Family Connections in 2026
In 2026, Sebastian Bach continued performing and discussing new music, keeping his family name in entertainment headlines. A particularly visible part of that activity was his collaboration with Paris, who played drums in his touring band.
An August 2026 interview with Ultimate Classic Rock featured Sebastian discussing plans for another studio album and identifying Paris among his musical collaborators. The interview documented the continuing father-son professional relationship.
Those developments offer current context about the Bierk family but should not be mistaken for updates about London himself. Recent mainstream reporting provides considerably more information about Sebastian and Paris than about London’s current occupation or personal activities.
Conclusion
London Bierk is the son of Sebastian Bach and Maria Aquinar, and the brother of Paris and Sebastiana Bierk. His family relationships are confirmed by longstanding entertainment coverage, including reports published when his parents announced their separation in 2010.
While his father remains a recognizable figure in hard rock and his older brother has established a public music career, London’s individual biography is less extensively documented. Understanding his family connections, the conflicting reports about his age, and the limits of reliable public information offers the clearest account of who he is.
