A close friend of William Wilberforce and John Newton. Though her conversion was not early in life, she was still a great influence in her day.
In her earlier years, she was a teacher, a playwright, and a writer.
She then quit all and took up her time with Sunday School and ministering to the poor.
At the age of 22 she became engaged to a man for about six years but he resisted marrying her. She then gained £200 in annuity which enabled her to quit her job as a teacher. She then became active in the London Society. It was not until 1785-87, that she became converted, though there is no precise day of her conversion. This is when she began fellowship with John Newton and William Wilburforce, and others in the Evangelical Society.
In retirement, she wrote best-selling works of Evangelical piety, she was a keen patron of the British and Foreign Bible Society and continued active in the anti-slavery movement. She also founded the Religious Tracts Society.
