Book excerpt: This book examines two linked Caithness Gunn families over many generations in places such as Scotland, Canada, Jamaica and Australia. It has many family trees, photographs and original documents including details of trips to Canada in the 1840s and Australia in the 1850s. Many letters from the mid 1800s are included. The book has many biographies including the Hon. Donald Gunn of Canada, William Gunn of Waranga Park, Sir John Gunn of Tormsdale and the Hon. John Alexander Gunn of New South Wales ('anthrax' Gunn). This book contains much original information showing how Gunns integrated into new lands. This work has taken many years and builds on documents held within the family and much detailed genealogical research. Two versions are available; a paperback black and white version and a deluxe hardback version with some colour photographs. The information and images are the same in both texts.
