Billie Eilish has been interested in music since she was 8. Although the teen sensation didn’t plan to become professional, she got great training as a musician – mostly due to her father, who is a big fan of music. Patrick listened to recordings of various genres – starting with the Beatles and ending with Avril Lavigne. He taught his son Finneas and daughter Billie to love music and in addition let them become homeschooled, so they had enough time to make their music experiments.
Patrick O’Connell knows how important it is for an artist to have enough time for creative work. That’s because he is busy in the entertainment industry, too. He is an actor, known by roles Billie’s father acted in the movies “Iron Man”, “The West Wing” and others.
Patrick Mead O’Connell is the son of James Bernard O’Connell and Jean Stone. Jean passed away in 1975. After that James re-married Beatrix W. O’Connell and spent 36 years with her till his death in 2014. Billie’s grandfather was a Harvard graduate. He was a famous writer and singer. Patrick grew up with a brother James Jr.
Patrick fell in love with acting in his young years, which he spent in Norwalk, Connecticut. He moved to Los Angeles when decided to pursue acting as a career. There he resides till now with his wife Maggie and their two children.

Billie’s father taught her to understand music, while her mother inspired her to create it. Maggie is a unique personality, who develops her own creativity – and helps her daughter and son create theirs.
She rose to fame as a singer, songwriter, and voice actress. Maggie spoke for the heroine of a role-playing video game “Mass Effect 2”, named Samara. Not long ago the woman co-wrote the movie “Life Inside Out”, where she starred in the company of her husband and son.
Really, Maggie can be proud of what she’s doing, but she is even more proud of the family she created. In her interview with “Your Teen” magazine the woman told, that they don’t lead a typical “Hollywood” lifestyle. Of course, each member of their family is a busy person, who visits auditions, and takes part in new projects, but if they have some free evening, surely they gather around a dinner table and enjoy the meal in the circle of the closest people.
By the way, Billie Eilish lived with her parents in their cozy, but not big house in LA even after she had become a star. The teen star resides with her parents in a two-bedroom home.
Maggie and her husband made up a difficult decision to let her kids study at home. She explained, that such a kind of getting education helped her kids to hear themselves and to understand, what their calling was.
Maggie May Baird is the daughter of William Norton Baird and his wife Edith May Shaw. Her mother passed away on November 3, 1987, from a sudden heart attack. Edith was 57 at the moment of her departure. Maggie still keeps her mother’s sweet image in her heart.
The actress Maggie Baird remains a great supporter of both her talented kids. In 2021 she appeared in her daughter’s documentary “Billie Eilish: The World’s a Little Blurry” as herself.

Finneas is that very person, who played the key part in his sister’s career. He authored a song “Ocean Eyes” and convinced Billie to sing it. Both had no idea, that their track would become so viral. Actually, that was the first stone, from which Billie Eilish started to build her career.
In addition to the role of Billie’s producer, Finneas is also a musician, songwriter, and actor. Viewers may remember him as Spencer from the film “Bad Teacher”, where he played opposite Cameron Diaz; as Alistair from the series “Glee” and in some other projects.
Finneas O’Connell was born and raised in Los Angeles. He was homeschooled, and according to his interview with “Your Teen”, he doesn’t plan to go to college in the nearest future. “It’s better to save the massive amount of money and spent it for the start of your career”, he tells.
Since September 2018 Finneas has been in a relationship with Claudia Sulewski, the YouTube star born in 1996. In October 2021he released the debut album “Optimist” through the label “Interscope Records” under the name Finneas. The full-length album consists of 13 songs.
