Her mother was a woman of independent fortune and her father an enterprising and successful man of affairs. He was the founder, in New York, of the Jockey Club, and his name figures conspicuously in the annals of the turf of both England and America, he having been one of its active patrons in the former country, whose racing system he introduced into America. His family migrated to Paris when his eldest daughter was in her eleventh year, and there his children grew up and were educated. Miss Jennie Jerome's artistic and musical gifts were carefully trained, and she has been considered ever since she made her _entrée_ into English society as one of its most accomplished pianists. Her name appears frequently on the programmes of concerts given in behalf of charity, and is always a powerful drawing card, for she plays with a clearness and delicacy of touch rarely attained by an amateur. France was at the height of its glories under the second empire when the Jeromes took up their residence in Paris. The court, presided over by one of the most beautiful women who ever wore a diadem, was characterized by almost unprecedented magnificence. Paris then, as now, led the world in all matters of personal adornment, and one feature in that _régime_ of luxuriant display, inaugurated by the Empress, is still felt to-day in every quarter of the globe where women make any pretence of following fashions in dress. She never permitted any woman to appear twice in her presence in the same gown. As a result, there dates from her brief era of leadership an extravagance in woman's dress that was before undreamed of, and which has had the effect of raising the details of a toilet from a subordinate to a ruling position among women in fashionable life, with a loss of much that gave a truer beauty to existence under a system when the sparkle of a woman's mind was of greater value than the flash of her jewels. Mrs. Jerome, a woman of wealth and taste, easily acquired a position of distinction in the fashionable life of the French capital at that time. Her eldest daughter meanwhile grew up with a reputation for great beauty, her fame increasing as the unusual gifts of her bright mind unfolded themselves. She was one of that group of clever and beautiful young girls with whom the Emperor and Empress from time to time surrounded the little Prince Imperial, and she participated at Compiègne in the memorable celebration of one of the few birthday anniversaries which fate accorded him. The Franco-Prussian war drove the Jeromes across the channel. They tarried in England during the days that marked the fall of the empire and the uprising of the Communards with their awful deeds of devastation. The summer of 1873 they passed at Cowes.
