St. Leger Stakes (Doncaster): so called from Colonel Anthony St. Leger, who founded them in 1776. The colonel was governor of St. Lucia, and cousin of the Hon. Elizabeth St. Leger (the lady Freemason).
The St. Leger Stakes are for both colts and mares. Those which have run in the Derby or Oaks are eligible.
