James Imray (1803–1870), worked originally in the stationery and account book publishing business. In 1836 Imray joined with Michael Blachford. The partnership flourished and soon began to compete with the larger firm of Norie and Wilson. In 1846 Imray bought out Blachford, and the company survived, led by his descendants, into the twentieth century, when it merged with Norie and Wilson.
