Like many successful Quakers, some of the Gurney family members found it difficult to reconcile their faith with their wealth. Joseph Gurney dedicated his life to his bank, his religion and good causes. He campaigned for prison reform and against slavery, and in 1837 went on a 3 year ministering tour of the West Indies and America, giving away one third of his share of the Bank's profits for the duration.
In 1896, in order to meet the competition of the joint stock banks, all the Gurney & Co. banks amalgamated with 11 other private banks to form Barclays Bank.
