“ In Edward VI's reign Whitchurch was established at the sign of the Sun in Fleet Street, and was on terms of intimacy with the protestant leaders. His press was busy until the king's death, and he was occasionally employed by the government to print official documents. Early in 1549 Whitchurch and Grafton printed the first edition of the Book of Common Prayer (Cardwell, Two Books of Common Prayer, pp. xxxviii-xliv) . ”
