The Heartbreaking Death Of Benedict Cumberbatch's Sister Tracy Peacock

As Daily Mail reported, Benedict Cumberbatch's now-deceased sister, Tracy Peacock, was the daughter of his mother, actress Wanda Ventham (above, with Cumberbatch), from her first marriage, to James Tabernacle. Cumberbatch's father is Timothy Carlton. Despite their age difference at the time, as a teenager, Peacock often looked after Cumberbatch when he was just an infant and toddler. Once, long after taking Cumberbatch to a freezing rooftop to calm him down, she realized that she had forgotten him. "She forgot about me," Cumberbatch said of the incident, per Daily Mail. "I mean, it was funny. She was in the kitchen with her friends and she suddenly saw the snow falling through the window."

Peacock showed just how close the half-siblings were when she spoke on Cumberbatch's behalf during his very public breakup from his girlfriend Anna Jones, back in 2012. "You would have to be a pretty smart cookie to keep up with him,' she said at the time, according to Daily Mail. "I think that is why possibly he has trouble with girlfriends."

According to Yahoo! Life, Peacock lived in Wiltshire, England, where she worked as a picture frame restorer. She leaves behind a husband and a 34-year-old daughter, Emily.
