In the 1870s, when Joseph Cairn Simpson (founder of California's first all-sports newspaper, Breeder and Sportsman) migrated west, he brought horses with him.

To finance his newspaper, he sold Marian to Theodore Winters, who owned California's best stallion, Norfolk, by one of America's greatest sires, Lexington.

After Norfolk retired, Marian produced another star horse: Yo Tambien, by turf champion Joe Hooker.

He retired lame after his last win in the Sheridan Stakes (the injury occurring during an exercise run), and Baldwin shipped him back to Rancho Santa Anita to begin his stud career.

Out of Americus Girl came the "flying filly," Mumtaz Mahal, and through her Mahmoud, Nasrullah, Royal Charger, and Tudor Minstrel.

Later, Baldwin's three other American Derby winners, Volante, Silver Cloud, and Rey El Santa Anita, were also buried there.
