Fev Rover is one of three winners out of Laurelita (High Chaparral), who won as a two-year-old. Laurelita is a half-sister to Zeyran (Galileo), dam of Rhoscolyn (Territories), placed in the Gr.3 Supreme Stakes.

The second dam Chervil (Dansili) also won at two. She is a half-sister to Light Jig (Danehill), a Grade 1 winner in the US, and to the Listed winners Lynton (Lyphard) and Battle Dore (Sanglamore). Light Jig is the dam of Seek Again (Speightstown), a Grade 1 winner in the US and a sire, Treble Jig, winner of the Gr.3 Jebel Ali Mile, and Scottish Jig, winner of the Listed Pride Stakes.

The third dam Nashmeel (Blushing Groom) won the Prix d'Astarte, then a Group 2, was placed several times at Group 1 level and has produced 11 winners.

Laurelita thus belongs to the extended family of the Grade 1 winners Light Jig and Seek Again.

Laurelita's 2-year-old Leveret (Invincible Army), a filly, was placed on her only start in England in 2023. Her last reported foal is a colt by Dark Angel, now a yearling.
