It was a close-knit family affair officiated by Rev. Louis Beasley-Suffolk, who performed a Roman Catholic service.

Reps for the actress did not return PEOPLE’s request for comment. But the public calendar for the church confirms a wedding for “A McGill” took place there last weekend.

The Irish actress revealed exclusively to PEOPLE during the 2018 Golden Globes — where she was nominated for best performance by an actress for Outlander — that McGill had popped the question after two years of dating.

“It happened over the break. I’m very happy,” she told PEOPLE as she showed off her new sparkler at the awards show.

Though they have kept their relationship out of the public eye, Balfe and McGill were photographed together at the 2017 Oscar Wilde Awards. He also accompanied her at the 2016 ceremony for Jodie Foster’s star on the Hollywood Walk of Fame.

They were first seen together in 2015 when a friend shared an Instagram video of Balfe sitting on McGill’s lap.
