I have to express an interest, having been brought up in one of the villages mentioned, knowing some of the people quoted, & going to a school founded by Lady Mabel Smith. It was a really fascinating read which I found hard to put down. It isn't easy to link the generations in a large family, but the author does it very well, the product of a great deal of research into the family, & much wider.
As the son of a miner I was particularly interested in the detail of the lives of the miners & their families, & the varying attitudes of the mine owners. The machinations of Royalty, the Government, & the committees explained so much of their struggle. Again the attention to detail gave credence & real life to the situations without the story dragging. In passing I would contrast the detail given of the Denaby situation with its wholesale evictions & legal threats, surely a milestone in industrial relations & the awful plight of many working people, with the lack of any mention in his book "The Edwardians" by local Labour politician Roy Hattersley. I found this book gave real insight & understanding of some of the important events in British history of the twentieth century, better than many textbooks, as well as a surprise unfolding of an aristocratic dysfunctional family. You are left asking "Are they all like that?"
