Joe Giles-Harris is an American professional football player who plays linebacker for the Cincinnati Bengals in the NFL. Born on April 1, 1997, in Nyack, New York, Giles-Harris played college football at Duke University before beginning his professional career with the Jacksonville Jaguars in 2019.
Beyond his football career, Giles-Harris comes from a family with a strong athletic background. His parents are John Harris and Lynn Giles-Harris, while his siblings include two brothers, William and J.T. Giles-Harris, and a sister named Margaret, also known as Maggie.
Giles-Harris has also been publicly linked to Sierra Stone, with whom he has a son named Blaize. Although he maintains a relatively private personal life, his family connections have been documented through university biographies, NFL media guides and public family records.
Joe Giles-Harris’s Girlfriend: Sierra Stone
Joe Giles-Harris has been publicly identified as the partner of Sierra Stone, with whom he shares a son.
According to the biographical website Famous Birthdays, Giles-Harris and Stone welcomed their son, Blaize, in December 2022.
Their relationship is also referenced in a family obituary published in April 2024 following the death of Sierra’s grandfather, Ronald D. Stone.
The obituary identifies Sierra J. Stone alongside Joe Giles-Harris and lists Blaize Harris as a surviving great-grandson.
These records establish a publicly documented family connection between Joe and Sierra, although the couple has generally avoided extensive media attention.
Unlike many professional athletes who regularly discuss their romantic relationships in interviews, Giles-Harris has focused primarily on football and his athletic development.
As of now, there is no sufficiently verified recent public announcement confirming whether Joe Giles-Harris and Sierra Stone remain together or have married.
Consequently, Sierra is best described as his publicly identified partner rather than definitively identified as his current wife.
Is Joe Giles-Harris Married?
As of now, Joe Giles-Harris’s marital status has not been conclusively established in reliable public reporting.
Although public family records identify his connection to Sierra Stone, they do not independently confirm a wedding date or provide an explicit announcement of marriage.
Giles-Harris has not made a widely documented public statement identifying a spouse or discussing a wedding ceremony.
Therefore, it would be inaccurate to claim that he is married without additional confirmation.
Joe Giles-Harris’s Children
Joe Giles-Harris has one publicly identified child, a son named Blaize.
Blaize Harris: Joe Giles-Harris’s Son
Blaize was reportedly born in December 2022 to Joe Giles-Harris and Sierra Stone.
His existence is supported by an April 2024 obituary for Ronald D. Stone, Sierra’s grandfather, which identifies Blaize Harris as a great-grandson.
Blaize was born during the period when his father was pursuing his professional football career after spending time with the Jacksonville Jaguars and Buffalo Bills.
Giles-Harris has generally kept his son’s private life away from extensive public reporting.
Although Blaize’s name and reported birth month are publicly documented, reliable sources provide limited additional information about him.
As of now, Blaize is Joe Giles-Harris’s only publicly identified child. There is no verified public announcement establishing that he has welcomed additional children.
Joe Giles-Harris’s Parents
Joe Giles-Harris’s Father: John Harris
Joe Giles-Harris’s father is John Harris, a former college football player who competed at Southern Connecticut State University.
According to his son’s official Duke University football biography, John earned three varsity letters while playing football from 1984 through 1986.
During that period, Southern Connecticut’s football program recorded an overall record of 18 wins and 11 losses.
John’s involvement in college football established an athletic background that would eventually extend to his sons.
Joe followed a similar path by becoming a college linebacker, while his older brother William also played the position at Gannon University.
His younger brother, J.T., pursued lacrosse rather than college football, eventually developing into an accomplished player at Duke.
The family’s sporting achievements demonstrate how competitive athletics became an important part of the Giles-Harris household.
John’s college football experience also meant that Joe grew up with a direct family connection to the demands of playing competitive football.
Although his father’s athletic background is well documented, reliable public sources provide limited additional information about John’s professional career and private life.
Joe Giles-Harris’s Mother: Lynn Giles-Harris
Joe Giles-Harris’s mother is Lynn Giles-Harris, whose identity is confirmed in official biographies published by Duke University and NFL organizations.
Lynn helped raise Joe and his siblings in a family where education and athletics were important parts of everyday life.
All three of her sons participated in college sports, with Joe and William pursuing football and J.T. achieving national recognition in lacrosse.
One documented example of Lynn’s enthusiasm for her children’s athletic achievements came during a December 2017 interview with Duke University.
When Joe was asked about his favorite holiday memories, he recalled enjoying Christmas breakfasts and dinners when the entire family gathered together.
During the same interview, he revealed that his mother had already claimed a large promotional photograph of him from Duke’s bowl game.
Joe humorously explained that she had made the decision before he could choose who would receive it.
He also mentioned that Lynn already had a similar photograph of his younger brother, reflecting her enthusiasm for both sons’ athletic careers.
The interview offered a glimpse into the family’s close relationship and their shared appreciation for important sporting milestones.
Although Lynn has been identified in several official sports biographies, her professional occupation and other personal details have not been consistently established in reliable public reporting.
Joe Giles-Harris’s Siblings
Joe Giles-Harris has three publicly identified siblings: an older brother named William Giles-Harris, a younger brother named J.T. Giles-Harris, and a sister named Margaret Giles-Harris.
Their identities are documented in official college and NFL media guides, including publications from Duke University and the Buffalo Bills.
William Giles-Harris: Joe Giles-Harris’s Older Brother
William Giles-Harris, also known as Will, is Joe Giles-Harris’s older brother and a former college football player.
He attended Gannon University in Pennsylvania, where he competed as a linebacker from 2009 through 2012.
During his four-year college football career, William recorded 181 tackles, 18 tackles for loss, five sacks, seven interceptions and 22 passes defended.
His performances demonstrated his ability to contribute both against the running game and in pass coverage.
William also earned Academic All-America honors during his senior season, reflecting his achievements in the classroom alongside his athletic responsibilities.
His college football career preceded Joe’s development into a standout linebacker at Duke University.
The brothers therefore share a strong football connection, having both played the same defensive position at the collegiate level.
William’s accomplishments represent another example of the athletic tradition within the Giles-Harris family.
As of now, reliable public reporting provides limited information about William’s professional career and personal life after completing his college football career.
J.T. Giles-Harris: Joe Giles-Harris’s Younger Brother
J.T. Giles-Harris, whose full name is John Thomas Giles-Harris, is Joe’s younger brother and a professional lacrosse player.
Born on July 17, 1998, J.T. attended St. Joseph Regional High School in New Jersey before enrolling at Duke University.
Unlike his older brothers, who pursued college football, J.T. concentrated primarily on lacrosse.
During high school, he established himself as a talented defensive player, earning multiple all-state and all-county selections.
He also played football during his school years, demonstrating the athletic versatility associated with his family.
J.T. subsequently joined Duke University’s men’s lacrosse program, where he became one of the team’s most accomplished defensive players.
As a sophomore in 2018, he started 19 of 20 games and recorded 22 caused turnovers and 26 ground balls.
His performances earned him third-team All-America recognition from the United States Intercollegiate Lacrosse Association.
He continued developing throughout his college career and earned further recognition for his defensive abilities.
Following college, J.T. pursued a professional lacrosse career in the Premier Lacrosse League.
According to the Cincinnati Bengals’ official player profile, he plays for the Denver Outlaws and has earned multiple professional all-star selections.
Both Joe and J.T. attended Duke University, creating a strong connection between the brothers and the university’s athletic programs.
Their achievements also illustrate the family’s success across different professional sports.
Margaret Giles-Harris: Joe Giles-Harris’s Sister
Margaret Giles-Harris, also known as Maggie, is Joe Giles-Harris’s sister.
Her identity is confirmed in the Buffalo Bills’ official 2021 media guide, which lists Joe’s siblings as William, J.T. and Maggie.
Margaret is also identified in J.T. Giles-Harris’s official Duke University lacrosse biography.
Unlike her brothers, who have received considerable public attention through their athletic careers, Margaret maintains a relatively private personal life.
Reliable public sources provide limited information about her education, profession and personal relationships.
There is also insufficient verified information establishing whether Margaret pursued competitive athletics.
Consequently, while her relationship to Joe Giles-Harris is confirmed, additional claims about her private life should not be presented as established facts.
