Meet Maggie Q’s Siblings: Andrea Quigley, Maria Quigley, and Nicole Quigley

Maggie Q, born Margaret Denise Quigley on May 22, 1979, in Honolulu, Hawaii, is an acclaimed American actress, model, and activist best known for her high-energy performances in action films and television series.

She rose to prominence with standout roles such as the title character in Nikita and appearances in major franchises like Mission: Impossible III and Divergent. Beyond acting, she is a passionate advocate for animal rights and environmental causes.

Maggie grew up in a multicultural household that shaped her worldview. Her mother, Kathy Quigley, emigrated from Vietnam, while her father, Dennis Quigley, is of Polish and Irish descent.

The two met during the Vietnam War when her father was stationed there, and their union created a rich blend of cultural traditions. Raised Catholic in a close-knit family in Mililani, Hawaii, Maggie later embraced Buddhism as an adult.

The youngest of five children, she has four older siblings—sisters Andrea Quigley, Maria Quigley, and Nicole Quigley, as well as at least one brother (possibly two half-brothers from her mother’s previous marriage).

While Maggie has occasionally shared glimpses of her family on social media—such as a 2024 birthday tribute to her brother or a National Siblings Day post—her siblings have largely chosen to live out of the public eye.

Maggie’s early years were marked by both academic focus and athletic excellence. She attended Mililani Waena Elementary, Wheeler Intermediate, and Mililani High School, where she excelled in cross country, track and field, and swimming.

After graduating in 1997, she briefly studied veterinary science at a private university on an athletic scholarship but left due to financial constraints, ultimately pursuing modelling work in Asia.

Andrea Quigley

Andrea Quigley is often noted as one of Maggie‘s older sisters, though specific details about her life are limited.

She has appeared in rare public glimpses, such as a 2018 Flickr photo from a Hawaii Senate event, where she was pictured alongside their mother (referred to as “Catherine” in the caption, possibly a nickname or error, but commonly known as Kathy) and Maggie.

This suggests Andrea maintains ties to Hawaii and occasionally joins her family for public or community appearances. Like her siblings, Andrea keeps a low profile, with no known involvement in the entertainment industry.

Maria Quigley

Maria Quigley is another of Maggie‘s older sisters, frequently listed alongside Andrea and Nicole in biographical summaries.

She shares the same multicultural upbringing in Hawaii and has been part of the close family unit that Maggie credits for her grounded personality.

Maggie‘s occasional social media nods to her siblings, like group photos on Siblings Day, hint at the warm relationships among them.

Nicole Quigley

Nicole Quigley rounds out the trio of sisters and is similarly private.

She has been spotted in family photos, including the same 2018 event where she attended with her daughter (Maggie‘s niece), Kalena Stensgaard, indicating Nicole has her own family.

This glimpse shows Nicole‘s role as a mother and aunt, contributing to the extended Quigley family network. Like her sisters, Nicole avoids the spotlight, allowing Maggie Q to shine while maintaining personal privacy.
