Hailee is related to Diamond Jubilee, born in 1897 to his owner/breeder, the future king, Edward VII. He is in Hailee's Lena Valenti line. He won many races, including the 2000 Guineas, Epsom Derby, St. Leger Stakes, Eclipse Stakes, Boscawen Stakes and Newmarket Stakes. So, yes, he is an English Triple Crown winner!! Hailee has Diamond Jubilee and Lord Lyon as her unique English Triple Crown winner to bring her and Violet's ETC relations to 11 out of 15!! He had flawless conformation, but a nasty temper. He once savaged a jockey and he was often rearing. He was not allowed to be beaten because his owner didn't want to ruffle his feathers or break his spirit! In England, he sired the important mare, Taormina who among others foaled Traumer, a stakes winner and stud in the United States. Taormina and Traumer are in Hailee's family tree!! Diamond Jubilee was sent to Argentina where he was a leading sire in 1914, 1915, 1916, and 1921. He passed in 1923.
