She was sired by Ahonoora, whose other offspring included The Derby winner Dr Devious. Ahonoora was a representative of the Byerley Turk sire line, unlike more than 95% of modern thoroughbreds, who descend directly from the Darley Arabian. Park Appeal's dam Balidaress was a moderate racehorse, winning three minor races, but proved a very successful broodmare: her other foals included Desirable (who won the Cheveley Park Stakes and was the dam of Shadayid), Alydaress, and Balistroika, the dam of Russian Rhythm.
