Maria Aquinar is best known for her long relationship and marriage to rock singer Sebastian Bach. Public entertainment records also identify her as Maria Bierk, which can make research about her confusing. The reliable public record is limited, so the clearest biography separates documented facts from the many unsupported details repeated online.
Who is Maria Aquinar?
IMDb lists Maria Aquinar as the birth name of Maria Bierk. The same profile identifies Sebastian Bach as her former spouse and records three children from that marriage.
Maria became publicly known mainly through her connection with Bach. Unlike her former husband, she has not maintained an extensively documented public career. That difference matters because many online biographies fill gaps in her history with claims that reliable sources do not clearly support.
Why she is also called Maria Bierk
Maria Aquinar and Maria Bierk refer to the same person in the entertainment records reviewed for this article. Sebastian Bach’s birth name is Sebastian Phillip Bierk, while “Sebastian Bach” is his professional name.
As a result, readers may find Maria listed under the Bierk surname in older entertainment databases and screen credits. IMDb’s Maria Bierk profile directly connects the name to Maria Aquinar.
Her marriage to Sebastian Bach
Maria Aquinar was married to Sebastian Bach, the Canadian-American singer best known for his work with Skid Row. IMDb lists July 26, 1992, as their marriage date and identifies them as parents of three children.
The marriage remains the main reason Maria’s name appears in entertainment coverage. However, her own documented public record should not be reduced entirely to her former husband’s fame.
What public records say about their family
IMDb identifies Maria and Sebastian as parents of two sons, Paris Francis Muir Bach and London Siddhartha Halford Bach, and a daughter, Sebastiana Maria Chantal Bach. The public record consistently supports that the couple had three children.
For broader context about the singer’s family history, Sebastian Bach’s Wikipedia biography also notes his relationship with Maria Aquinar and their three children.
The 2010 separation
Public sources place the couple’s separation in 2010. Sebastian Bach’s Wikipedia biography specifically identifies April 2010 as the month of their split.
The exact date when the divorce became legally final is less clear in publicly available sources. Some celebrity databases provide a precise date, while other accounts use different timelines. For that reason, this article does not present one final-divorce date as established fact.
The private reasons for the end of the marriage also should not be treated as fully documented. Sebastian Bach has spoken publicly about his own experience of the breakup, but Maria Aquinar has kept much more of her perspective private. A careful biography should not turn one person’s comments or internet speculation into a complete explanation.
Maria Aquinar’s documented screen appearances
Maria Bierk has a small number of documented entertainment credits. IMDb lists her in Sebastian Bach: Forever Wild, Supergroup, and On Our Own.
The IMDb page for Sebastian Bach: Forever Wild lists Maria Bierk among the documentary’s credited participants. IMDb also lists her as herself in several episodes of Supergroup.
These credits support describing Maria as someone with limited documented television and entertainment appearances. They do not, by themselves, establish a long-running acting, modeling, management, or business career.
What is not publicly confirmed about Maria Aquinar
The biggest problem with many Maria Aquinar biographies is not a shortage of information. It is the tendency to treat repeated claims as verified facts.
Age and early life
A clearly authoritative public source confirming Maria Aquinar’s exact birth date was not identified during this research. Online pages give conflicting details about her age and early background.
Therefore, this article does not publish an exact age, birthday, birthplace, education history, or family background as fact.
Career and current life
Some websites describe Maria as a model, fitness personality, wellness professional, or manager. The public sources reviewed for this article do not provide enough evidence for a detailed professional biography.
Her documented screen credits are real. Beyond those appearances, her current work and day-to-day life remain largely private.
Net worth
There is no reliable financial disclosure that establishes Maria Aquinar’s personal net worth. Estimates found on biography websites often lack transparent evidence.
For that reason, no net-worth figure appears here. A former marriage to a successful musician does not prove a person’s current assets or finances.
