Career
She had been working as a healer for many years, employing "fasting spittle, a little liquor of ‘a red complexion’, touch, and prayer", but came to national prominence after she was featured in a local newspaper in August 1748, when she was about 70 years of age. Her fame became such that by the following month she was receiving 600–700 visitors a day seeking her assistance, and she soon decided that she would only see those she had dealt with before or who were suffering from deafness. Bostock was reported to be a regular churchgoer and a person of great faith by William Harding, the minister of her church, whose son claimed that she had cured his lameness.
Nothing is known of her after 1749.
