The sire of Gribaldi is the Trakehner top progenitor Kostolany who performed at Grand Prix level himself! In 1995 Kostolany made history by siring both the Sieger (Champion) stallion and the Sieger mare. Alongside Gribaldi, Kostolany is the sire of many approved stallions including; Bertone, Showmaster, Silvermoon, Tolstoi, Sans Souci and Polansky.
The famous mare Kasette from "Hauptgestüt Trakehnen" forms the basis of Kostolany`s dam line and products of this line include the Olympic Dressage Horse Immanuel (Munich 1972) as well as the Trakehner progenitors Kapitan and Kassius.

In 1995, Gribaldi`s full sister Georgina was the best three year-old mare at the Central Mare Inspections in Hessen. Gribaldi`s dam, Gondola II became an Elite mare in 1995 on the basis of her offspring. Additionally Gondola II is the dam of the approved stallion Goldino who was performing at Prix St. George level at the age of seven years-old. The first crop from this stallion produced two approved sons (Trakehner Stallion Selections 1995/1996), Up to Date and Uljanoff who became Reserve Champions after Gribaldi! Gondola II is by the dressage progenitor Ibikus who was both (Champion) and four times "Championatssieger".

The successes of Gribaldi progeny are almost too many to mention. Many mares are very highly placed at the Mare Selections, in the various performance tests in Deurne and Drachten and a great number are successful in their IBOP tests. Many offspring of Gribaldi have participated in the PAVO CUP for four and five year-old Dressage Horses and many were selected for the Semi-Finals and the Finals.
