I have been working on family history for 36 years and during that period I have purchased a number of books on the subject. Most of them have been disappointments, but this one is an exception. It is well written, timely and - so far as I can determine - accurate. Within the first half hour of opening it I had found some information about the 1841 census that cleared up a puzzle that had been frustrating me. The only complaint that I have is that this book will probably cause me to buy others, which won't be as useful as this one.
