Last Updated on November 11, 2026 by Bernald Sanders

Liam O’Brien is a Canadian professional ice hockey player who plays as a forward for the Utah Mammoth in the National Hockey League (NHL). Born on July 29, 1994, in Halifax, Nova Scotia, Canada, he is widely recognized for his physical playing style, energetic personality, and popular nickname, “Spicy Tuna.”

Beyond his hockey career, Liam O’Brien is a husband and father. He is married to Adèla O’Brien, and the couple welcomed their daughter, Leilani Eva O’Brien, in 2024. His parents are Shawn and Susan O’Brien, and he has three siblings: Kate, Rowan, and Callum O’Brien.

Liam O’Brien’s Wife: Who Is Adèla O’Brien?

Liam O’Brien is married to Adèla O’Brien, a woman originally from the Czech Republic.

Unlike many professional athletes who keep their marriages entirely private, O’Brien has openly discussed his wife and their family life in interviews with hockey reporters.

Although the exact date and location of their wedding have not been widely documented, their marriage is confirmed by multiple reputable sports publications, including the Deseret News, KSL Sports, and ALLCITY Network.

In June 2024, O’Brien spoke enthusiastically about his wife and their future in Utah after signing a three-year contract with the franchise.

He explained that he and Adèla were excited about establishing a home in Utah, describing the state as an appealing place to raise their family.

Adèla’s Czech background has also influenced their household. During an interview published by ALLCITY Network, O’Brien explained that he was learning Czech because he wanted to communicate with his wife and daughter in the language.

He mentioned using the Duolingo language-learning application and expressed his intention to improve his Czech as his daughter grows up speaking the language.

Although Adèla is publicly identified as O’Brien’s wife, information about her profession, educational background, and early life remains limited.

Liam O’Brien’s Children

Liam O’Brien has one publicly confirmed child, a daughter named Leilani Eva O’Brien.

He and his wife, Adèla, welcomed their first child in 2024. The birth was publicly announced in June of that year.

Becoming a father represented a major personal milestone for the Canadian hockey player, particularly as he was preparing for a new chapter with the Utah franchise.

Leilani Eva O’Brien – Liam O’Brien’s Daughter

Leilani Eva O’Brien is the daughter of Liam and Adèla O’Brien.

Her arrival was announced in June 2024, attracting attention from fans of the former Arizona Coyotes and the newly established Utah Hockey Club.

In an interview following his contract extension, Liam expressed his excitement about introducing his daughter to relatives in Halifax, Nova Scotia.

He also discussed how becoming a father had changed his perspective on life.

During a family-focused interview with ALLCITY Network, O’Brien explained that parenthood had given him a greater appreciation for the work and sacrifices involved in raising children.

The couple selected the name Leilani because they liked its sound and versatility. O’Brien noted that their daughter could also be affectionately called Leilinka in Czech.

He hopes that Leilani will grow up speaking Czech, reflecting her mother’s heritage and the family’s multicultural background.

No additional children have been publicly confirmed for Liam and Adèla O’Brien.

Liam O’Brien’s Parents

Liam O’Brien was born to Shawn O’Brien and Susan O’Brien, who raised him in a supportive family environment in Halifax, Nova Scotia.

Both parents have influenced Liam’s character, hockey career, and commitment to helping others.

Liam O’Brien’s Father: Shawn O’Brien

Shawn O’Brien is Liam O’Brien’s father.

He has been actively involved in the hockey community in Nova Scotia and played an important role in supporting his son’s athletic ambitions.

In December 2023, an official NHL article about Liam’s participation in adaptive hockey programs highlighted Shawn’s community involvement.

According to Liam, his father frequently helped people within the local hockey community, including young athletes seeking guidance and families facing challenges.

Shawn’s willingness to assist others helped shape Liam’s understanding of responsibility and community service.

He also supported his son’s pursuit of a professional hockey career, including the challenges associated with leaving home at a young age to play competitive junior hockey.

When Liam earned a place with the Washington Capitals in 2014, Shawn followed his son’s progress closely and celebrated the achievement with his family.

The Washington Post documented the family’s excitement following Liam’s unexpected rise from an undrafted junior player to an NHL roster spot.

Liam O’Brien’s Mother: Susan O’Brien

Susan O’Brien is Liam O’Brien’s mother.

She has a professional background working with children with autism, an experience that has influenced her son’s charitable interests.

In December 2023, Liam participated in an adaptive hockey event organized by Mikey’s League in collaboration with the Arizona Coyotes.

He explained that the initiative was particularly meaningful because his mother had previously worked with children facing similar developmental challenges.

Susan’s professional experience helped inspire Liam’s interest in supporting inclusive sporting activities for children with disabilities.

Alongside her husband Shawn, Susan also encouraged her four children to pursue their ambitions and supported Liam throughout his development in junior and professional hockey.

Her influence extends beyond sports, particularly through the values of compassion, generosity, and community involvement that Liam has discussed publicly.

Liam O’Brien’s Siblings

Liam O’Brien has three siblings: Kate O’Brien, Rowan O’Brien, and Callum O’Brien.

All three were identified by Liam himself in a personal article published by Sportsnet about his experiences in Canadian junior hockey.

Although he spent several years living away from home while developing his hockey career, Liam maintained strong connections with his brothers and sister.

Kate O’Brien – Liam O’Brien’s Sister

Kate O’Brien is Liam O’Brien’s sister and one of the four children of Shawn and Susan O’Brien.

Kate was mentioned in Liam’s first-person Sportsnet article, in which he discussed missing his hockey-playing siblings while living away from home.

Although she comes from an athletic family, detailed information about Kate’s competitive hockey career, education, and occupation has not been widely published.

She maintains a relatively private life compared with her brother, whose professional hockey career has attracted public attention.

Rowan O’Brien – Liam O’Brien’s Brother

Rowan O’Brien is one of Liam O’Brien’s brothers.

Like Liam and the other children in the family, Rowan participated in hockey during his younger years.

In an interview published by PHNX Sports in November 2023, Liam discussed how music helped maintain his close relationship with his brothers.

He explained that they regularly exchanged songs, demonstrating that their relationship extends beyond their shared interest in hockey.

Further information about Rowan’s professional career and personal life is not extensively documented in public sources.

Callum O’Brien – Liam O’Brien’s Brother

Callum O’Brien is Liam O’Brien’s other brother.

He was also identified in Liam’s Sportsnet article as one of his hockey-playing siblings.

Callum grew up in the same sports-oriented family environment as Liam, Kate, and Rowan.

Like Rowan, he shares an interest in music with Liam, and the brothers have maintained their connection through regular exchanges of songs.

Although Callum’s family relationship is publicly confirmed, details about his education, employment, and personal relationships remain largely private.

Liam O’Brien’s Grandfather: Peter O’Brien

Liam O’Brien has also spoken about his late grandfather, Peter O’Brien, who was a journalist and enjoyed writing poetry.

In a November 2023 interview with PHNX Sports, Liam recalled that his grandfather would write poems about his hockey games and send them to him.

Peter’s passion for writing influenced Liam’s own creative interests.

In addition to hockey, Liam has enjoyed creative writing, poetry, and songwriting.

He studied creative writing through Acadia University and has continued to express an interest in writing throughout his professional hockey career.

How Liam O’Brien’s Family Influenced His Hockey Career

Liam O’Brien’s family played an important role in helping him pursue professional ice hockey.

He learned to skate in Cole Harbour, Nova Scotia, and began playing organized hockey in Montreal before progressing through several Canadian youth hockey programs.

At a young age, he left home to attend Notre Dame in Saskatchewan, where he played competitive hockey.

His development continued in the Quebec Major Junior Hockey League (QMJHL), where he represented the Rimouski Océanic, Rouyn-Noranda Huskies, and Sherbrooke Phoenix.

Living away from home presented challenges, but his parents remained supportive throughout his junior career.

Although O’Brien was not selected in the NHL Entry Draft, he signed with the Washington Capitals organization in 2014.

He made his NHL debut with Washington on October 9, 2014, beginning a professional journey that later included time with the Colorado Avalanche, Arizona Coyotes, and Utah franchise.

His family continued to play a central role in his life as his career developed.

The arrival of his daughter in 2024 and his family’s move toward establishing roots in Utah gave him additional reasons to value stability away from the rink.
