Ronan Farrow is fondly remembering his late brother.
Mia Farrow's son shared a sweet tribute to his younger sibling, Thaddeus Farrow -- who died last week at age 27 -- writing, "Rest in peace, brother. I never knew anyone stronger, or who overcame more."
Thaddeus, who was a paraplegic due to polio, was pronounced dead at Danbury Hospital in Connecticut after law enforcement found him with life-threatening injuries in his car.
According to the Office of the Chief Medical Examiner in Connecticut, Thaddeus died of a gunshot wound to the torso. His death has been ruled a suicide.
"We're devastated by the loss of Thaddeus, our beloved son and brother," Mia tweeted last week, linking to the American Foundation for Suicide Prevention. "He was a wonderful, courageous person who overcame so much hardship in his short life. We miss him. Thank you for the outpouring of condolences and words of kindness."
Thaddeus was adopted by Mia from Calcutta, India, in 1994, and was one of 10 children the 71-year-old actress has adopted.
