If you, like myself, have a mixed British heritage & are aware of it then this book is absolutely*useless*. I saw a recommendation for it & so got myself a used copy. It is a good book if you want to know about British festivals but have no experience or knowledge of them. If you have family scattered in the British Isles you will learn nothing new.
