House of Guinness Cast and Characters

The four Guinness siblings lead the story: Anthony Boyle as Arthur Guinness, Louis Partridge as Edward Guinness, Emily Fairn as Anne Plunket, and Fionn O’Shea as Benjamin Guinness. Boyle plays the eldest brother forced to leave his London life to run the brewery. Partridge portrays Edward, the ambitious younger brother deeply tied to the family business. Fairn’s Anne and O’Shea’s Benjamin bring emotional depth as the overlooked siblings.

Other key roles include James Norton (Happy Valley) as the powerful brewery foreman Sean Rafferty and Jack Gleeson (Game of Thrones) as Byron Hedges, who embarks on a dramatic journey to New York. Niamh McCormack plays Irish Republican activist Ellen Cochrane, while Seamus O’Hara stars as her twin Patrick.

The supporting cast is equally strong: Danielle Galligan as Lady Olivia Hedges, Dervla Kirwan as Aunt Agnes Guinness, Ann Skelly as Adelaide Guinness, Michael McElhatton as John Potter, Jessica Reynolds as Lady Christine O’Madden, Elizabeth Dulau as Lady Henrietta St Lawrence, Michael Colgan as Reverend Henry Gratton, David Wilmot as Bonnie Champion, and Hilda Fay as the mysterious Sultan.

The mix of Irish and British talent adds depth to the series, while the lavish sets and period costumes immerse viewers in the late 1800s brewing empire.

Critics praise the performances of Boyle and Partridge for bringing sibling tension to life, while Norton’s intense turn as Rafferty has been widely discussed. The show’s historical angle and modern storytelling style by Peaky Blinders creator Steven Knight have made it a strong candidate for award buzz.

Fans on social media note the mix of drama, politics, and family intrigue feels fresh for a period series. Its success may inspire more historical dramas on Netflix, especially those rooted in real-life industries and power families.
