The Rev. John Charles Cox (1844-1919) was perhaps one of the most influential English local historians of the nineteenth century. Anyone studying early modern Derbyshire quickly comes across his work. He published dozens of books, including calendars of local records, a four-volume history of Derbyshire churches, and a detailed study of All Saints, Derby.
A brief biography of Reverend Cox – who was born in Parwich – has just been published on the “Mercurius Politicus” blog. If you have an interest in our local history, then it’s well worth a read.

Hello and thanks for the link! It’s always nice to know someone’s reading my posts. By way of background I’m currently researching the life of a 17th century writer who was born in the parish of All Saints in Derby in 1612, so have been doing lots of digging into life in the town at that point.
