Game of Thrones star Gemma plays Marian Lister, Anne's quieter and much put-upon younger sister, while Timothy West plays their father Captain Lister and Gemma Jones stars as their aunt Anne.

But viewers immediately spotted a familiar face from Game of Thrones in the opening episode – Gemma Whelan aka Yara Greyjoy. Whelan plays the protagonist’s long-suffering sister Marian Lister.

Besides her romantic relationship with fellow landowner Ann Walker (Sophie Rundle), the period drama also highlights Lister's connection with her sibling Marian (Gemma Whelan).

Meanwhile, Marian (Gemma Whelan) was scolded by her sister when she revealed she planned to marry Mr Abbott (John Hollingworth), who the rest of the family disapproved of.

Whelan plays Anne Eaton, a cousin of the Bamber family. Joining Whelan in the cast is Cressida Bonas, Freddie Fox, and fellow GoT alum, Alfie Allen. Watch White House Farm on ITV on Jan. 8 at 9 p.m.
