He has a sister named Cara.

His mother Lois Wiltse O’Brien worked as a quality assurance trainer and an educator. She died in 2016 from cancer. He wrote on Twitter in 2018:

”My mother battled with cancer on and off throughout her life. In the lead up to her passing two years ago, it robbed her of her personality, and finally, stole her from our lives.”

Liam also wrote:

”It was the hardest, darkest moment of my life.”

During high school, O’Brien started getting into acting. He once said about his childhood:

”I grew up in Weehawken, New Jersey, and everyone I went to school with sounded like they were in The Sopranos.”

He went to New York University Tisch School of the Arts.

O’Brien went on to say:

”I was daydreaming about being a half-elf in grade school, so the last several years have just felt like coming home.”
