The Downton Abbey actress' family has thanked fans for their condolences following the death of her partner John Dineen over the weekend.
A statement from the Dockery family to The Mirror read: "The family is very grateful for the support and kindness they have received but would kindly request that they are left to grieve in private."
According to the Irish Examiner, the 34-year-old passed away at a hospital in Cork, Ireland on Sunday morning (13 December) following an illness. No further details are known.
Michelle, who played Lady Mary Crawley in Downton, is believed to have been introduced to businessman Richard through her Downton Abbey co-star Allen Leech. She has always kept her private life out of the spotlight, saying only: "I have a wonderful man in my life from Ireland. We were introduced by Allen Leech. That's all you need to know."
