Ruth Wilson on 'Mrs. Wilson' and Her Real, Polygamous Grandpa, the Spy

Ruth Wilson’s miniseries Mrs. Wilson (PBS, March 31, 9 p.m. ET, check local listings), in which she plays her real-life grandmother Alison Wilson, is a true story wilder than her fictional Showtime hit The Affair. Ruth’s grandpa Alec Wilson (played by Game of Thrones’ Iain Glen), Alison’s husband, was a British spy and best-selling novelist. Writer Tony Parsons has said, “Without Wilson, it is very unlikely there would have been Bond, Bourne and Smiley.” 

Alec was fired in disgrace, possibly as a Spy Who Came In From the Cold-like ruse involving the spy chief having him investigated: Anthony Blunt, the Queen’s art adviser and secretly Stalin’s mole in the British secret service. Wilson spent time in prisons (including the grim one that inspired The Shawshank Redemption), went broke, was forgotten and died in 1963. Then his widow, Alison, discovered she wasn’t his only wife — and became a nun.

Ruth Wilson, who is single, recently discovered dozens of new relatives, including her half-brother Mike Shannon of the Royal Shakespeare Company. She makes her own Shakespearean debut April 4 on Broadway in King Lear, starring Glenda Jackson. She explained her family drama at the February 2019 Television Critics Association meeting.

How she discovered her family scandal

My grandmother wrote a memoir about meeting Alec, falling in love with him and then finding out about his betrayal. I never knew [my grandfather]. There was no mention of him. Once she gave us this memoir, we still didn’t talk to her about it. It was bizarre. A year after she died, we had correspondence from two other people saying, “I think we’ve got the same dad.” So we worked out that [Alison] is one of four wives, not one of two. 

How her grandfather’s spy life was a great cover for polygamy

She met him at MI5 [the British secret service] — she worked there as well. So she knew that he worked for the service, and a lot of things he was saying were true [but secret due to his spy job]. That was often a huge fight and tussle within herself. 

What grandma Alison the nun was like

She was very reserved, very quiet. She had this fiery passion inside her, which I never saw. Her memoir gave me real insights to this emotional landscape inside her, which was huge and passionate. Even as a nun, she still had a vanity about her. She always looked immaculate. My mom remembers having to clean the mirrors because my granny left hair spray [film] from doing her hair.

Meeting the secret relatives

We’ve had family reunions where we had name tags and met each other in a room, talking about this mysterious grandfather, or father. It was just an extraordinary story [we] felt had to be told. And me being in the business, it was sort of down to me to do it. We had a family screening [of Mrs. Wilson] with all 55 members, from age 6 months to 97. And there was a four-minute silence, and everyone was in tears. It was an amazing bonding experience.
