A guide can be defined as something that provides a person with guiding information. To find one that helps organize a very complex period of history found in many family trees, is called "The Cromwellian Gazetteer, An Illustrated Guide to Britain in the Civil War and Commonwealth"
by Peter Gaunt.
Organized first by country [England, Wales, Scotland, and Ireland], it then guides one county by county through the conflict that ends in what is called "The Commonwealth Period". For the genealogist, if one has a family member involved during this period of time, it becomes very hard to get a grasp of this conflict. The sites involved during this crisis are shown in brief summary [many in pictures]. A detailed itinerary of the life of Oliver Cromwell is included which helps establish chronology for much of the conflict. An interesting point of view it is.
First published in 1987 by Alan Sutton Publishing Limited, it was printed in Great Britain by Redwood Books, Trowbridge, Wiltshire.
