For some reason, the sire of Rosolanka is given as Ilderim OA, the father of among others Bakszysz 1901. That would not be possible, as Rosolanka then would have been born before her own sire! However, Ursula Guttmann 1968 'Die Abstammung der Polnische Araber' states that Ilderim, a Persian stallion, was imported some time between 1837 and 1845 by the Branicki stud at Biala Cerkiew. This horse may be Rosolanka's sire.
