Unable to purchase well-performed mares he bought half-sisters to top performers but not necessarily outstanding horses themselves.
His early acquisitions included Persis and Lady Marie (both foaled in 1923), who established families of major stakes-winners in New Zealand and Australia.
[2] Another very successful Trelawney Stud stallion was Alcimedes (GB) (by Alycidon), a winner over distances from 7 to 10½ furlongs.
During the early 1990s Trelawney Stud was purchased from Robert Holmes à Court by the Taylor family.
In 2006, Trelawney stood the top juvenile, Van Nistelrooy (USA) (by Storm Cat), a US$6.4 million yearling.
