Tis the season of the witch! Stumbled across this very vague story…
Janet Horne was the last person to be executed for witchcraft in the British Isles. In 1727, she was stripped, covered in tar, led through the town of Dornoch, and burned alive. The poor woman was accused by her neighbors, which most likely came about because she was going senile. Her daughter was arrested too- she had a deformity in her hands and feet. The neighbors told stories of Janet of riding her daughter like a pony to meet with the devil. After a quick trial, she was sentenced to death. Her daughter escaped, but no one knows what happened to her after that.
One slight glitch in this story- “Jenny Horne” was a slang term for a witch in Scotland. Janet Horne may not have been her real name, but given to her over the years as the story was passed down because her real name was unknown.
