P.S. By the way, my family knew Michael Davies personally. In fact, he visited our home more than once while in the United States. To this day we still have the gift he and his wife brought to us on their first visit. He was one of the kindest, most humble and unassuming people you'd ever meet. He was always joking in a self-deprecating way. You'd never know he was the towering intellect and historian behind these incredible books.
