Jane Ainsworth's second book - Keeping their Beacons Alight: The Potter Family of Barnsley and their Service to Our Country - is a comprehensive family history inspired by the surviving letters and other memorabilia of two young brothers who were killed in action in the First World War. It concentrates on the military service of many of their relations during the first half of the 20th Century. Frank and Eddie Potter, sons of Barnsley Builder Charles Dalton Potter, featured in her first book published by Helion & Company in March 2016: Great Sacrifice: the Old Boys of Barnsley Holgate Grammar School in the First World War. This memorial book about the 76 men listed on the War Memorial includes a detailed history of Barnsley Grammar School. It received critical acclaim for Jane's meticulous research and use of school records to provide biographies for these well educated young men who were prevented from achieving their full potential. It emphasised their life stories within the context of their families rather than their military experiences. Keeping Their Beacons Alight has allowed Jane to make full use of her painstaking and tenacious research skills to write the biography of the Potter family, with an emphasis on their military service. She has uncovered an impressive number of relations who joined the Territorial Army before 1914 and who served during the First and Second World Wars in a wide variety of roles. Jane used her genealogical expertise to produce the extended family trees and consulted several relations, who generously shared information and photographs for use in this book; they were fascinated and surprised by many of her findings. She followed clues wherever they led, spending time searching the internet and going through collections of records to provide background information, such as Barclays Bank, Barnsley Cordwainers' Society and Freemasonry. She used War Diaries and Officer Records from The National Archives as well as visiting Regimental Archives and Museums to flesh out individuals' military service. Barnsley Chronicle provided a wealth of supplementary details. The Potter family is an extraordinary one with their zealous response to the calls to arms, but Jane hopes that it will encourage others to delve deeply into their family history and reveal hidden gems.
