She is a half-sister to two black-type-placed winners, Wahdan (Siyouni), who won over 1900m and was third in the Gr.2 Prix Eugene Adam, and Talbah (Style Vendome), a winner over 1500m who was placed in the Gr.3 Prix Imprudence.

Second dam Lamorlaye (Danehill Dancer) won over 1300m in France and bred five winners. She is a half-sister to Jazzique (Kingman), a winner in the US who was Grade 2-placed.

Third dam Love To Dance (Sadler's Wells) did not win in 12 starts but was third in the Gr.2 Blandford Stakes, and had three winners. A daughter of Lagrion, she is a half-sister to Dylan Thomas (Danehill), a six-time Group 1 winner and sire, Queen's Logic (Grand Lodge), the unbeaten winner of the Gr.1 Cheveley Park Stakes, and Homecoming Queen (Holy Roman Emperor), winner of the Gr.1 1000 Guineas.

The family is also connected to Serpentine (Galileo), winner of the Gr.1 Derby in 2020, whose second dam is Lagrion.
