House of Guinness family tree: Meet them before Season 2

Netflix renewed House of Guinness for a second season in June 2026, with cameras set to roll again in early 2027. The eight-episode first season introduced the four adult children of Sir Benjamin Lee Guinness after his 1868 death, and viewers are already mapping who controls the brewery, who stays sidelined, and who might flip alliances when filming resumes. A quick family tree keeps the next batch of episodes from feeling like a new cast list dropped without warning.

Arthur claims the title

Arthur Guinness, played by Anthony Boyle, arrives from London as the eldest son and presumed heir. Educated at Eton, he spent his twenties away from Dublin and now steps into the boardroom with a London polish that the Dublin staff notices immediately. His return sets the tone for inheritance disputes that stretch across both seasons.

Real-life Arthur Edward Guinness later became Baron Ardilaun, yet the series keeps the focus on the immediate scramble for control after his father’s funeral. The character’s outsider perspective lets writers contrast English manners against Irish business realities without leaving the brewery gates.

His presence also anchors the show’s central question of legacy versus competence. Arthur holds the legal advantage, but the staff and his siblings watch to see whether he can run the place or merely inherit it.

Edward runs the numbers

Younger brother Edward, portrayed by Louis Partridge, handles day-to-day brewery operations and pushes for modernization. Where Arthur brings status, Edward brings spreadsheets and an appetite for expansion that mirrors the real Earl of Iveagh’s later global reach.

The series positions Edward as the sibling most willing to court risk, whether that means new export markets or quiet political maneuvering. His ambition collides with Arthur’s caution, creating the first sustained conflict inside the family offices.

Viewers tracking the renewal news already expect Edward’s storyline to widen in Season 2, especially once the brewery’s balance sheet meets external Fenian pressure and shifting British tax rules.

Anne stays outside the ledger

Anne Plunket, née Guinness and played by Emily Fairn, is the only daughter and therefore barred from direct inheritance under period law. Married and living at a slight remove, she still influences family decisions through social leverage and private counsel.

The show uses Anne to dramatize the legal walls women faced in Victorian Ireland, yet it also gives her scenes that reveal how information travels through drawing rooms faster than board minutes. Her limited stake does not equal limited insight.

Renewal coverage suggests Anne’s role expands in Season 2 as marital alliances and potential scandals intersect with the brewery’s public image.

Ben wrestles his demons

Benjamin, or Ben, the middle brother portrayed by Fionn O’Shea, battles alcoholism and gambling debts that threaten to become public liabilities. Named for his father, he carries both the family name and its most visible vulnerabilities.

The series presents Ben as the emotional core of the sibling group, someone whose personal failures test the limits of family loyalty and public discretion. His arc supplies the private stakes that temper the larger corporate chess game.

With production not slated until 2027, writers have time to decide whether Ben’s struggles lead toward redemption or further fracture the already tense succession plan.

Aunt Agnes holds the memory

Dervla Kirwan’s Aunt Agnes supplies generational continuity and occasional sharp commentary from the sidelines. She remembers the brewery’s earlier triumphs and quietly tracks which of her nephews respects that history.

Agnes also functions as an informal archivist, reminding viewers of the real Guinness family’s long timeline beyond the four siblings. Her presence softens the pace when boardroom scenes dominate.

Industry observers note that period dramas often use such elder figures to deliver exposition without exposition dumps, and early reviews credit Kirwan with keeping the family tree legible.

Ellen brings the outside in

Niamh McCormack plays Ellen Cochrane, a Fenian organizer whose political work intersects with the Guinness household through both conviction and proximity. Her storyline introduces republican pressures that the brewery’s English-leaning leadership would rather ignore.

Ellen’s presence widens the canvas beyond inheritance law into the larger question of Irish identity in the 1860s. The character’s ties to at least one sibling create romantic and strategic complications that renewal coverage flags for deeper exploration.

Viewers comparing the series to Steven Knight’s earlier work already expect the Fenian thread to intensify once cameras return.

Sean watches the gates

James Norton’s Sean Rafferty serves as charismatic brewery foreman and occasional confidant to the siblings. His working-class vantage offers a ground-level view of decisions made upstairs.

The character also supplies romantic tension and a potential bridge between the Guinness inner circle and the city’s labor networks. Norton’s casting guarantees American viewers recognize at least one face amid the Irish ensemble.

Early social-media chatter after Season 1 centered on whether Rafferty’s loyalties stay with the family or shift toward Ellen’s cause, a question the writing team can answer across the next season.

Adelaide adds the wit

Ann Skelly’s Adelaide Guinness appears as a witty cousin whose social calendar intersects with the main siblings at key moments. She provides comic relief and an outside perspective on how the family is perceived beyond St. James’s Gate.

Though not in the direct line of inheritance, Adelaide’s observations often cut through the siblings’ self-seriousness. Her limited screen time in Season 1 already generated fan discussion about possible expansion.

Renewal timing gives the writers room to decide whether Adelaide remains a peripheral voice or steps into a larger supporting role.

Real history meets scripted stakes

The series draws from documented Guinness family history while rearranging timelines and motivations for dramatic effect. Real Arthur, Edward, Anne, and Benjamin existed, yet the show compresses decades of brewery growth into the immediate aftermath of Sir Benjamin’s death.

This approach keeps the family tree manageable for new viewers while still nodding to the later global empire the real brothers helped build. The renewal announcement signals that Knight intends to stretch the same core group across at least one more chapter.

Audience tracking after the September 2025 premiere showed strong completion rates for the eight episodes, suggesting the sibling conflicts landed with Succession-minded viewers ready for another dynasty round.

Next steps for the tree

With production not expected until early 2027, the cast list for Season 2 remains fluid, yet the core four siblings and their immediate circle are locked. Viewers mapping the House of Guinness family tree now can track who gains ground, who loses leverage, and whose private struggles surface once filming resumes.
