Rob Roy took his stallion performance test as a three-year old premium stallion in Prussendorf with a total index of 116.23, finishing on an excellent sixth place. All of the stallions ahead of him were already four years old. His uniformly high scores for rideability (118.40/4^th place) and his talent for jumping (112.00/7^th place) are noteworthy.

His sire Rubin-Royal won the main premium in Oldenburg, took eighth place at the Nürnberg Burg Pokal and then placed in Grand Prix dressage. In 2007 he won the VTV Dressage Stallion of the Year award. More than 20 of his sons have been licensed, including the Reserve Champion and State Champion, Rubin Cortes.

His dam, St.Pr.St. Glory Dream, did an outstanding job at her broodmare performance test, placed in tests for young riding horses and produced St.Pr.St. Red Charmer (by Rubin-Royal) and a show jumper named Starlight (by Sao Paulo). The dam's sire Glorieux was the 1988 Riding Horse Bundeschampion and then competed in medium (M/A) level dressage. The granddam, St.Pr.St. Sally, who is also the dam of Picado (by Pablo), an advanced (S) level winning dressage horse, is a half-sister of the licensed and internationally successful show jumper Grundsteins Erbe (= Eurocommerce Rome, by Glorieux)/Gerco Schröder/NED as well as the licensed stallion Glorioso Noir (by Glorieux; private stallion USA) and Fortunatus (by Futuro).

The Hanoverian dam line of Grafenalp is also known for numerous licensed stallions such as the international show jumper Griseldi L (by Grosso Z)/Ulrich Kirchhoff and Fortunatus (by Futuro), Feingau (by Furioso II; private stallion Oldenburg), London (by Landjonker; private stallion SUI), Landkönig (by Landadel; private stallion USA), Lascaro K (by Lordanos; State Stud Schwaiganger), Picknick (by Pik Bube II; private stallion) and Weissherbst (by Wendepunkt, State Stud Celle) and many sport horses that are successful in advanced level, some of which were sold at auctions.
