‘Blue Bloods’ Family Guide: Meet the Reagans as CBS Introduces Spinoff Boston Blue

For more than a decade, Blue Bloods has centered on one family that represents law enforcement, justice, and tradition in New York City: the Reagans. As CBS expands the Blue Bloods universe with the upcoming spinoff Boston Blue, fans old and new may be revisiting the family that made the franchise a long-running success.

At the heart of Blue Bloods is Frank Reagan, the New York City Police Commissioner, played by Tom Selleck. Frank is a firm but fair leader, guided by his strong moral compass and deep Catholic faith. As both a public figure and family patriarch, he often struggles to balance the demands of his job with his responsibility to his children.

Frank’s eldest son, Danny Reagan (Donnie Wahlberg), is a seasoned NYPD detective known for his intense dedication and sometimes aggressive tactics. Danny’s work on the streets often places him in morally gray situations, but his loyalty to victims and his family never wavers.

Erin Reagan (Bridget Moynahan) serves as an Assistant District Attorney, bringing a legal perspective to the family’s law enforcement discussions. Practical and principled, Erin frequently clashes with her brothers over justice versus procedure, offering a necessary counterbalance to their policing instincts.

The youngest Reagan sibling, Jamie Reagan (Will Estes), began the series as a Harvard Law graduate who chose policing over a legal career. Over time, Jamie has grown into a thoughtful and capable officer, eventually rising through the ranks while navigating complex ethical dilemmas.

The family’s legacy is deeply shaped by loss as well. Frank’s wife, Mary Reagan, passed away before the series began, and his son Joe Reagan, a detective, was killed in the line of duty. Their absence continues to influence the family’s values and decisions, reinforcing the sense of sacrifice that defines the Reagans.

What truly sets Blue Bloods apart is the Reagan family dinner—a weekly ritual where personal conflicts, professional disagreements, and moral debates unfold around the table. These scenes underscore the show’s focus on family unity, even amid disagreement.

With CBS introducing Boston Blue, the franchise signals an expansion beyond New York City while keeping the spirit of Blue Bloods alive. Though details about how closely the spinoff will connect to the Reagans are still emerging, the original family remains the foundation of the series’ identity.

As Blue Bloods evolves and its world grows, the Reagans’ commitment to justice, family, and service continues to define the legacy that made the show a staple of network television.
