‘Boston Blue’ Family Tree: Meet the Reagans and Silvers of ‘Blue Bloods’ Spinoff MD19

The highly anticipated Blue Bloods spinoff, Boston Blue, has officially premiered, trading the classic Sunday dinner in New York for Friday Shabbat and Baptist services in Massachusetts. The show successfully transplants fan-favorite Detective Danny Reagan (Donnie Wahlberg) from the NYPD to the Boston Police Department (BPD), but its true genius lies in introducing a compelling, multi-generational law enforcement family to replace the void left by the bulk of the Reagans: The Silvers.

Boston Blue maintains the core DNA of the original series—a combination police procedural and family drama—by focusing on how duty, faith, and political tension play out around the dinner table. This time, the table is shared by a complex, blended family that mirrors the Reagans’ commitment to justice but adds layers of modern complexity, cultural diversity, and professional rivalry.

Here is a breakdown of the two intertwined families—the familiar Reagans and the powerful new Silvers—who form the foundation of Boston Blue.


🗽 The Reagan Legacy in Boston

Detective Danny Reagan relocates to Boston following an incident involving his younger son, marking a new chapter for the character and the continuing expansion of the Reagan legacy.

Danny and Sean: The Next Generation

Danny Reagan is the anchor, forced to navigate a new city and a new police culture. His move is driven by family: his younger son, Sean Reagan, has followed the family tradition into policing, but was forced to take a job as a rookie cop with the BPD due to a hiring freeze in New York. Sean’s presence is the emotional tether to the original show, and his partnership with Jonah Silver (the Silver family’s rookie) bridges the two dynasties.

In a poignant nod to the original show’s family theme, Danny is now in a romantic relationship with his former NYPD partner, Detective Maria Baez, who is confirmed to appear in a recurring role, ensuring the connection to New York remains strong.


🌃 The Silver Dynasty: Boston’s Law and Order

The Silver family is the beating heart of Boston Blue, a prominent, multi-generational dynasty of law enforcement and legal professionals who gather for Shabbat dinners on Fridays, replacing the Reagans’ famous Sunday tradition. The family is also blended and multi-faith, with Baptist roots and Jewish conversions, providing a rich, modern complexity to the classic family drama formula.

The Silver Family Tree

Mae Silver Gloria Reuben Boston District Attorney (DA) Lena’s mother; converted to Judaism after marrying the late Ben Silver.

Ben Silver (Deceased) N/A Judge Mae’s late husband; the Jewish patriarch of the family.

The Blended Faith and Leadership

The Silver family structure introduces compelling dynamics:

  1. Mae Silver (The DA): As the Boston District Attorney, Mae Silver holds a position similar to the role Erin Reagan holds in New York, instantly creating friction with the police side of the family. She is the biological mother of Lena and Jonah, and converted to Judaism when she married Ben Silver, who was a respected Judge before his death.

  2. Lena Silver (The Partner): Danny Reagan’s new partner, Detective Lena Silver, is a rising star in the BPD. She is navigating a difficult path as she works under her stepsister Sarah and must deal with her mother, the DA. Lena is also in the process of completing her conversion to Judaism, a decision supported by her Baptist grandfather, Reverend Peters.

  3. Reverend Edwin Peters (The Patriarch): Played by the legendary Ernie Hudson, Reverend Peters serves as the spiritual and philosophical anchor of the family. He struggled with Mae’s conversion but ultimately supports his family’s diverse paths, providing the wisdom often delivered by Frank Reagan in the original series.

  4. Sarah Silver (The Boss): Lena’s stepsister, Sarah Silver, is the Superintendent of Detectives—Lena’s boss. The competitive tension between the two stepsisters, who are both high-achievers in law enforcement, is a major source of internal family drama that mirrors the professional friction seen between the Reagan siblings.

  5. Jonah Silver (The Rookie): The younger brother, Jonah Silver, is a rookie patrol officer. His quick friendship and partnership with Sean Reagan ensures that the youngest generation of both families are immediately intertwined, creating shared experiences and loyalties.


🤝 The Intertwined Destinies

The true success of Boston Blue lies in its ability to quickly and convincingly weave the Reagan and Silver family trees together.

  • Professional Partnership: The pairing of Detective Danny Reagan and Detective Lena Silver is the central procedural partnership. Their contrasting styles—Danny’s street-wise aggression versus Lena’s rising-star ambition—drives the weekly cases.

  • The Rookie Duo: The parallel careers of rookie officers Sean Reagan and Jonah Silver provides a fresh, youthful perspective on the difficulties of starting a law enforcement career in a new city. Their shared experiences and bond mirror the early partnership dynamics of the original Blue Bloods cast.

  • The Family Dinner: By establishing a new multi-faith, multi-generational family dinner tradition on Shabbat, Boston Blue retains the crucial element of the original show: the family table as the place where the professional and personal dramas of law and order are dissected and debated. This setting is where Danny is integrated into the Silver clan, forcing him to adapt to a new set of political and familial rules.


🔑 Conclusion: A New Blue Dynasty

Boston Blue is much more than just a change of scenery; it is a thoughtful evolution of the Blue Bloods franchise. By relocating Danny Reagan and his son Sean, the show maintains its legacy connection. By introducing the deeply established, multi-layered Silver family—led by the political power of the DA, the spiritual guidance of the Reverend, and the competitive drive of the BPD leaders—it establishes a new, complex, and highly compelling dynasty.

The two families’ destinies are now intertwined in the high-stakes world of Boston law enforcement. Fans can expect Boston Blue to deliver the same tense crime drama and heartfelt family conflict they loved in Blue Bloods, now refracted through the unique prism of the Reagans and Silvers as they fight to protect their city and their kin.
