A very thorough and well-written book on a sprawling topic. This is well-organised and the appendices are extremely helpful. The author has also included excellent examples to demonstrate the ideas and documents in action.
My only criticism of this book is that there was repetition of some ideas, statistics, explanations etc that made it feel a little tedious in parts. If these were removed, it would make for a more streamlined read. Nevertheless, this is an essential read for someone who is starting their foray into surnames as it is so jam packed with great content.
Note: As with any book on genealogy, there are some references that are no longer up to date because datasets have either moved to a new platform or projects have been completed on digitising documents since the book’s publication.
