Ingoldsby, dam of grade I winner and millionaire Formal Gold, died June 17 of colic at the veterinary clinic of Hagyard-Davidson-McGee Associates near Lexington. Owned by Rodes and Cathie Kelly, the 17-year-old mare was in foal to Unbridled's Song. She had produced a Miswaki filly March 17 for the Kellys in a foal-share arrangement with jockey Mike Smith. Miswaki is the grandsire of Formal Gold.Bred by Pope McLean and Michael J. Fonzone, Ingoldsby raced at Woodbine, winning her second start before suffering an injury. The Kellys acquired her in lieu of a board bill after she produced her first two foals. Her first offspring, Maple Lake, was a Canadian stakes winner.Formal Gold, a son of Black Tie Affair, was foaled in Canada. He won half his 16 starts and earned $1,533,600. As a 4-year-old in 1997, he scored grade I wins in the Woodward Stakes and Donn Handicap and grade II wins in the Brooklyn and Philip H. Iselin Handicaps, the latter in track-record time. Ingoldsby that year was a finalist for Canadian Broodmare of the Year.Ingoldsby (Screen King--Dorothy Kay, by Irish Castle) produced 10 foals, five of which are winners. The Kellys plan to race her Miswaki filly born this year.
