Who Is Maria Aquinar? Early Life in Canada
Maria Sandra Muir Aquinar was born in December 1963 in Canada. Naturally striking, athletic, and fiercely loyal, Maria possessed a grounded personality that balanced the high-strung creative energy of the performing arts scene. She grew up in a supportive Canadian household, completing her education and pursuing fitness and lifestyle interests.
How Maria Aquinar Met Sebastian Bach
In the mid-1980s, Maria crossed paths with a teenage vocalist named Sebastian Bierk (who adopted the stage name Sebastian Bach). At that time, Bach was fronting regional Canadian club bands such as Madam X, living out of battered suitcases and dreaming of rock stardom. Maria recognized Sebastian’s extraordinary vocal gifts and magnetic charisma before major record labels even knew his name.
When Jon Bon Jovi’s management team discovered Bach and brought him to New Jersey to front Skid Row, Maria was right by his side. When Skid Row’s self-titled 1989 debut album exploded onto the Billboard charts—spawning anthems like “Youth Gone Wild,” “18 and Life,” and “I Remember You”—Maria provided the emotional stability that kept Sebastian anchored.

Having welcomed their first son, Paris, in March 1988, Maria and Sebastian officially tied the knot on July 26, 1992. Their wedding was a major celebration attended by prominent rock musicians, producers, and close family members. In a music subculture notorious for fleeting, disposable romances, Maria and Sebastian’s relationship was viewed as an inspirational anomaly.

- London Bierk (born 1994): Grew up to pursue creative and professional ventures outside the music touring grind.
- Sebastiana Bierk (born 2007): Their youngest daughter, whose birth brought immense warmth and domestic joy to their New Jersey residence.
