 She helped finance and guide early Methodism and was the first principal of Trevecca College, Wales, established in 1768 to train Methodist ministers.With construction of 64 chapels in England and Wales, plus mission work in colonial America, she is estimated to have spent over £100,000 on these activities, a huge sum when a family of four could live on £31 per year.A regular correspondent of George Whitefield and John Wesley, she is also remembered for her adversarial relationships with other Methodists.
