Although he was sired by a Derby Stakes winner out of a mare by a St. Leger Stakes winner, Jacopo showed a fair amount of the brilliance associated with his second dam's sire, Sundridge, and was a champion at 2. He trained on well enough to be a stakes winner at 1½ miles at 4 but was something of a hard-luck horse after his juvenile season. He sired plenty of winners in the United States but few of significant class and was better known as a sire of broodmares.

Pedigree notes
Jacopo is inbred 5x5 to the important broodmare Quiver. He is a half brother to Foray II (by Tetratema), the English champion juvenile male of 1936, and is a half sister to 1933 English co-champion 3-year-old filly Eclair (by Ethnarch), dam of 1945 Middle Park Stakes winner and important sire Khaled (by Hyperion), stakes winner Lady Electra (by Fairway; second dam of the good English juvenile Eudaemon) and stakes winner Eclat (by the Hyperion horse Stardust). Eclair also produced Vicenzia (by Sansovino), dam of stakes winner Drama II (by Nearco); Celaeno (by Fairway), second dam of three stakes winners including 1964 Suburban Handicap winner Iron Peg; and stakes-placed Emali (by Umidwar), second dam of four stakes winners including French Group 3 winner Afayoon and third dam of multiple French champion and influential sire Blushing Groom.
Jacopo and his siblings were produced from the juvenile winner Black Ray (by 1914 St. Leger Stakes winner Black Jester), whose dam Lady Brilliant (by Sundridge) was a minor stakes winner at 3. The next dam in Jacopo's tail-female line, the Ayrshire mare Our Lassie, won the 1903 Oaks Stakes and also produced Sweet Lassie (by Orme), dam of Criterion Stakes winner Sunfire (by Sundridge). Produced from the Melton mare Yours, Our Lassie is a half sister to 1908 St. Leger Stakes winner Your Majesty (by Persimmon), a two-time champion sire in Argentina.
