Foaled in 1918 by Justice Brooke-The Miss Stokes, Tilly Brooke was bred by George T. Moore, Dromore Farms, St. Clair, Michigan. At the beginning of her 1924 season, after training with T. W. Murphy and owned by John G. Elbs of Rochester, New York, Tilly Brooke trotted in 1:59 in a special match race at Toledo, Ohio. This time was the race record for trotters for 13 years, until it was broken by Greyhound in 1937. Tilly Brooke then went on to Lexington to win the Transylvania in 2:01 1/4, completing a chain of eleven consecutive Grand Circuit victories for the year.
