Ethel Beatty was a rich mother, Peter had birth complications that affected his eyesight and she was the foremost hostess in England.
On January 1, 1891, Ethel married Arthur Magie Tree in an opulent ceremony held at the home of her parents, 1905 Prairie Avenue in Chicago. Together, they were the parents of three children, only one of whom survived to adulthood: Peter had birth complications that affected his eyesight and muscle control for the rest of his life, thought to originate from a venereal disease carried by Ethel. In her obituary, it was noted that "her beauty and personality made her one of England's foremost hostesses. While David Beatty benefited by Ethel's wealth, it was not a happy marriage, "I am the most unhappy man in the world", David once said, "I have paid terribly for my millions".
