Between 1877 and 1914, Essex parishes formed part of the (then new) Diocese of St Albans. It was created in response to the great increase in population in areas adjoining London. The counties of Essex and Hertfordshire were taken from the Diocese of Rochester (to which See Essex was transferred from London in 1846). Thomas Legh Claughton, the first Bishop, transferred from being Bishop of Rochester. His place of residence was Danbury Palace, now a management training centre and public park. John Wogan Festing succeeded him in 1890, then Edgar Jacob in 1903.
Bound Diocesan records for this period are held at the ‘Hertfordshire Archives and Local Studies’ at the County Council offices in Hertford. Whilst searching for information on Blackmore, I came across the following information relating to the High Country parishes.
