Thanks to the diligence of Mark Mawtus, I have acquired the publishers file copy of "Genealogical Notes & Memoirs of the Smithson Family" by George R Smithson. It was published in 1906 by Seeley and Co. Ltd, 38 Great Russell Street, London. The Latter Day Saints hold a copy on Microfilm. The Smithson Association in the United States also hold an original. This is the full text with illustrations but you will find the layout differs slightly from the book to suit publishing in this format.
