Following the death of William Caslon I in 1766, his son William Caslon II took over the Caslon Foundry, running it with the assistance of his wife, Elizabeth Cartlich, until his own death in 1778. Elizabeth Caslon then continued to manage it jointly with her two sons, William Caslon III (1754–1833) and Henry Caslon (c.1755–1788) trading as "Elizabeth Caslon and Sons". Henry died in 1788, and in 1792 William III sold his share of the business to his mother and his sister-in-law, Elizabeth Rowe, Henry's widow: the two Elizabeth Caslons continued to run it until the elder Elizabeth's death in 1795. As a result of a legal dispute over the terms of her will, the Foundry was then thrown into Chancery and put up for auction in 1799. It was bought by the younger Elizabeth Caslon, who took into partnership a distant relative, Nathaniel Catherwood. Both partners died in 1809. The subsequent proprietors were: Henry Caslon II and F. F. Catherwood, 1809–1821; Henry Caslon II, H. W. Caslon and M. W. Livermore (trading as Caslon, Son and Livermore), 1821–1840; Caslon & Son, 1840–1850; H. W. Caslon and Co., 1850–1873. H. W. Caslon died in 1873, when the Foundry was acquired by T. W. Smith and partners. However, the Company name remained H. W. Caslon and Co. Ltd., and continued running until 1937, when it was acquired by Stephenson Blake.
