Cy Fair is out of the winning Remarqued (Arch). She is the mare's fourth foal and so far her sole winner.

Her second dam, the multiple stakes winner Citizen Advocate (Proud Citizen), won several Listed races and was Grade 3-placed. She produced three winners, among them Crimson Advocate (Nyquist), also a multiple stakes winner, who took two Group 2 races at the Royal Ascot meeting and was third in the Gr.1 Falmouth Stakes. She is also the grandam of the Listed-placed winners Danielita R (Cairo Prince) and Flowers For Me (West Coast).

Third dam Twilight Service (Horse Chestnut) was unraced and produced three winners.

Citizen Advocate's half-sister Come a Callin (Dixie Union), a winner, produced Caledonia Road (Quality Road), champion among 2-year-old fillies and winner of the Grade 1 Breeders' Cup Juvenile Fillies, Officiating (Blame), winner of several graded stakes including two at Grade 3 level, and the Listed winner One Of A Kind.

Remarqued's yearling is a filly by Omaha Beach, she foaled a filly by Nyquist in March 2025, and she was covered again by Nyquist.
