Maria Aquinar is best known as the former wife of Sebastian Bach, the Canadian rock singer who fronted Skid Row from 1987 to 1996, and as the mother of their three children, Paris, London and Sebastiana. The couple were together for about 18 years before they separated in April 2010.

Maria Aquinar is the former wife of Sebastian Bach and the mother of Paris, London and Sebastiana Bach. She was married to Bach for about 18 years, was known publicly as Maria Bierk during the marriage, and separated from him in April 2010. No dependable public record establishes her birth date, her early life, her current occupation or her net worth, so claims on those points should be treated as unverified.

Who Is Maria Aquinar?

Maria Aquinar is the former wife of Sebastian Bach, the Canadian hard rock singer best known as the frontman of Skid Row from 1987 to 1996. Maria Aquinar is also the mother of the couple’s three children, Paris, London and Sebastiana. Her public identity comes almost entirely from that marriage and from her role as a mother, because she did not build a widely documented independent career in entertainment, modeling, fitness or public advocacy.

Maria Aquinar met Sebastian Bach in the mid-1980s, during the early years of his music career. Bach was born Sebastian Philip Bierk on April 3, 1968, in Freeport, Bahamas, and was raised in Peterborough, Ontario, Canada. He joined Skid Row in 1987, and the band’s debut album Skid Row (1989) and its follow-up Slave to the Grind (1991) made him one of the most visible rock singers of the era. Contemporary news reports and professional photographs from the marriage years generally identified her as Maria Bierk, not Maria Aquinar, and the name Maria Aquinar became the common form only in newer online coverage.

The search interest in Maria Aquinar follows a familiar pattern for celebrity spouses who stay private. Readers search for her age, her birth date, her net worth, her current life and her children, and biography sites answer with confident numbers. This article keeps the two apart, so readers can see what is known and what is only repeated.

Digital Geek Spot states a fact only when a dependable source supports it, and labels a repeated claim unverified when no source supports it. Browse more celebrity profiles in the General category.

Why Was Maria Aquinar Known as Maria Bierk?

Maria Aquinar was known as Maria Bierk during her marriage because Bierk is Sebastian Bach’s legal surname. Sebastian Bach was born Sebastian Philip Bierk, and he performs under the stage name Sebastian Bach. News reports covering the couple’s separation used the name Maria Bierk, and professional photo archives documenting their appearances together also used Maria Bierk.

Both names refer to the same person. The newer online coverage more commonly calls her Maria Aquinar, while the contemporary coverage from the marriage years used Maria Bierk. Reliable public records do not fully explain when or why she used each surname, and no dependable source confirms a legal name change or a return to a maiden name after the divorce.

This name split causes real confusion for readers. Some profiles treat Maria Bierk and Maria Aquinar as two different people. Others list Maria Bierk as a nickname, which misses the point: it was the married name used in public records of the time, not a nickname. A search for Maria Bierk returns the same marriage, the same children and the same 2010 separation, because the two names describe one life.

The name question also explains why some details are hard to verify. A private person who changed the name she used in public leaves a thinner paper trail, and the trail that exists sits under two names.

When Did Maria Aquinar and Sebastian Bach Marry and Separate?

Maria Aquinar and Sebastian Bach were married for about 18 years and separated in April 2010. Bach announced near the end of December 2010 that they had been separated since April. He said they had tried to resolve their differences for their family but had decided to separate because those differences were irreconcilable. Reports published around the announcement stated that the couple planned to proceed with their divorce in 2011.

The table below sets out the marriage timeline as the documented record supports it.

Three points in that timeline deserve care. First, the wedding date of July 26, 1992 appears in secondary profiles, but contemporary coverage focused on the length of the marriage rather than confirming that exact date, so it stays unverified. Second, some profiles claim the divorce was finalized in September 2010, while others claim it happened in the mid-2000s or in 2011. Without a publicly accessible court record confirming the precise date, the established chronology supports an April 2010 separation followed by a divorce recorded as 2010. Third, the reason for the split should not be stated as fact beyond Bach’s own words.

Bach married Suzanne Le in August 2015, and the couple lives in Las Vegas. That date is verified, and it marks the clear end of the Aquinar chapter of Bach’s public personal life.

Who Are Maria Aquinar’s Three Children?

Maria Aquinar has three children with Sebastian Bach: two sons, Paris and London, and a daughter, Sebastiana. Paris is the eldest, London is the second son, and Sebastiana is the youngest child and the only daughter. Contemporary reports about the couple’s separation identified all three children by name, and coverage of the family also mentioned them.

Paris Bach was born in March 1988, which makes him the only child whose birth date is fixed by the public record. He followed his father into music, and he plays drums in Bach’s solo band. That detail is verified in Bach’s biography, which lists Paris Bach as the drummer in the current solo band lineup. Paris also accompanied his parents to a publicly photographed event in April 2010, around the time of the separation.

London Bach is the couple’s second son. Reports published in early 2011 described London as 14 at the time, which places his birth in about 1996 or 1997.

Sebastiana Bach is the youngest child and the only daughter. Reports published in early 2011 described Sebastiana as three at the time, which places her birth in about 2007. Her full name is reported as Sebastiana Maria Chantal Bach. One popular profile misnames her “Sebastien Jr.”, which is wrong on two counts: she is a daughter, and her name is Sebastiana, not Sebastien.

The entire family appeared on the VH1 reality series I Married…, which documented the marriages and households of well-known performers. Maria Aquinar’s participation gave viewers a brief look at her family life, but it did not establish television as a continuing profession for her. The family also attended public events together, including the T.J. Martell Foundation’s 30th Anniversary Gala in New York in October 2005, an appearance at MTV’s TRL studios in October 2007, and a Tribeca Film Festival premiere on April 24, 2010. Professional photographs also place Maria Aquinar and Bach at a New York launch gathering on September 22, 2010.

What Is Maria Aquinar’s Net Worth?

No dependable public record establishes Maria Aquinar’s net worth, so any figure should be treated as an unverified estimate. Popular profiles give figures between $1 million and $2 million, but none of them cites a source, a filing, a business record or an interview that supports the number. The honest answer is that her net worth is not publicly known.

The two most quoted figures show the problem. One profile estimates her net worth at around $1 million. Another estimates it at $1-2 million, described as a post-divorce figure. Neither profile explains how the number was reached, what assets it counts, or whether it reflects a divorce settlement, personal earnings or a guess.

Readers should treat celebrity net worth figures with care in general, and with extra care here. The $1 million and $1-2 million figures are best read as placeholders that biography sites use when they have no real number, not as facts.

Maria Aquinar spent about 18 years married to a singer whose band sold 20 million albums worldwide by the end of 1996, and whose debut and second albums went multi-platinum. Until a dependable source reports a figure, this article records her net worth as unverified rather than repeating a number it cannot support.

What Is Known About Maria Aquinar Today?

Dependable sources do not establish Maria Aquinar’s current occupation or recent public activities. Her documented public identity remains closely connected to her former marriage and her role as the mother of Paris, London and Sebastiana. Her most visible appearances occurred while she and Bach were together, particularly through I Married… and several public events between 2005 and 2010. Since the separation, she has kept her life private, and the public record has gone quiet.

Some call her a model, a television personality, a fitness professional or a public advocate. Others place her in New Jersey or describe her as a veganism advocate. None of these claims rests on a dependable public record. Her appearances at public events during the marriage do not support descriptions of her as a professional model or an independent television personality, and no dependable record establishes a separate career in fitness, wellness or advocacy.

A former model career, a fitness business, a New Jersey residence and a December 23, 1963 birth date all appear in profiles of Maria Aquinar, and all of them lack a source. The birth date is a good example. Two profiles list December 23, 1963, one adds the middle names Sandra Muir, and a third profile says her birth date is not publicly disclosed. The third profile is the honest one. Claims about Maria Aquinar’s birth date, education, nationality and early life remain poorly supported, and they often appear as facts on biography websites without reference to authoritative records.

She is the former wife of Sebastian Bach, the mother of three adult children, and a private individual who has stayed out of public view since her marriage ended. Her eldest son Paris plays drums in Bach’s solo band, which keeps a family connection to Bach’s music in public view. Beyond that, her current life is her own, and no verified reporting describes it.

Maria Aquinar vs Maria d’Aquino and Other Name-Alikes

Maria Aquinar is a different person from Maria d’Aquino, Maria Pilar Aquino, Maria D. Aquino and Maria Aquino-Duran, and search results mix them up because the names look alike. The table below separates them so readers do not carry facts from one woman’s life into another’s.

Maria d’Aquino was an illegitimate daughter of Robert the Wise, King of Naples, and was beheaded in 1382 on the orders of King Charles III. Maria Pilar Aquino is a professor emerita of theology at the University of San Diego and the author of a 1992 book on Latin American theology from the perspective of women.

Readers who search for Maria Aquinar should also watch for the reverse error: profiles that borrow the December 23, 1963 birth date or the Canadian birthplace from one another without a source. The verified record for Maria Aquinar contains no birth date at all, and this article leaves that field blank rather than repeating an unsourced date.

What Do Popular Profiles Get Wrong About Maria Aquinar?

Popular profiles of Maria Aquinar get the birth date, the divorce date, the daughter’s name, the net worth and the career wrong, because most of them repeat each other instead of checking a record. The table below lists the main claims, what the record actually supports, and the verdict on each.

The pattern across these errors is consistent. The most recent and most careful profile, published in August 2026 and updated in September 2026, flags the unverified claims and sticks to the documented record. The older profiles, published around 2024, present the same claims as facts with no sourcing.

Readers who want reliable information about Maria Aquinar should look for the profile that admits what it does not know, not the one that answers every question with a confident number.

She is a private individual who gained public attention through her marriage and her family, not through an independent entertainment career.

What is Maria Aquinar’s age?

Maria Aquinar’s age is not publicly verified, because no dependable source establishes her birth date. Some biography sites list December 23, 1963, which would make her 62 in November 2026, but that date appears without a source and other profiles say her birth date is not publicly disclosed. Until a dependable record confirms a birth date, her age cannot be stated as fact.

Who are Maria Aquinar’s children?

Maria Aquinar has three children with Sebastian Bach: Paris, London and Sebastiana. Paris is the eldest and was born in March 1988; he plays drums in Bach’s solo band. London is the second son, and reports from early 2011 described him as 14. Sebastiana is the youngest child and the only daughter, and reports from early 2011 described her as three.

When did Maria Aquinar and Sebastian Bach divorce?

Maria Aquinar and Sebastian Bach separated in April 2010, and the divorce is recorded as 2010. Bach announced the separation near the end of December 2010 and said the couple planned to proceed with divorce in 2011. Claims that the divorce happened in the mid-2000s conflict with the documented timeline, and no public court record confirms a precise final date.

What is Maria Aquinar’s net worth?

Maria Aquinar’s net worth is not publicly known, because no dependable record establishes any figure. Popular profiles estimate it at $1 million or $1-2 million, but none cites a source, a filing or a financial disclosure. Those figures should be treated as unverified estimates, not as facts.

Is Maria Aquinar the same person as Maria Bierk?

Yes, Maria Aquinar and Maria Bierk are the same person. Maria Bierk was the name used in contemporary news reports and professional photographs during her marriage to Sebastian Bach, because Bierk is Bach’s legal surname. Newer online coverage more commonly uses Maria Aquinar, while the marriage-era coverage used Maria Bierk.

What does Maria Aquinar do now?

No dependable public source establishes Maria Aquinar’s current occupation or recent public activities. Her most visible appearances occurred during her marriage, through the VH1 series I Married… and public events between 2005 and 2010. Claims that she works as a model, television personality, fitness professional or advocate go beyond what her confirmed record supports.

Conclusion

Maria Aquinar is best known as Sebastian Bach’s former wife and the mother of Paris, London and Sebastiana, and that short description is the part of her story the public record actually supports. She was married to Bach for about 18 years, was known publicly as Maria Bierk during the marriage, and separated from him in April 2010. Her eldest son Paris plays drums in Bach’s solo band, which keeps one visible thread between her family and the music that made Bach famous. Everything else that biography sites publish about her, the December 23, 1963 birth date, the $1 million net worth, the modeling and fitness career, the New Jersey residence, rests on repetition rather than on a record, and this article records those claims as unverified rather than repeating them as facts.

For Maria Aquinar, what is known is enough: a long marriage to a rock singer, three children, a quiet life since the marriage ended, and a name that changed in public use from Maria Bierk to Maria Aquinar.
