This book contains the booklet "The Background to the Rise of Freemasonry in North Wales in the 18th and 19th Centuries" by Harold Senogles, which was first published in 1972. This booklet itself builds off the Bicentenary Souvenir of The Province of North Wales 1727 - 1927 which was produced by R. H. Gough Smallwoood for the 200th anniversary of the Province of North Wales. It is an informative look back at the rise of Freemasonry in North Wales, and the creation of the Province of North Wales. We hope this book will be a valuable resource for anyone wishing to research the Freemasonry in North Wales. Profits from this book are going to charity.
