Old Child Mare The General Stud Book gives the pedigree of the Old Child Mare as: "Bred by Mr Child, or Mr Burdett, got by Sir T Gresley's Bay Arabian called Bay Roan, out of Vixen, by The Helmsley Turk, out of The Royal Mare, which was Dodsworth's dam" [GSB 1:6] The Turf Register notes that "The OLD CHILD MARE (grandam of Whimsey) was also bred by Mr Burdet, and got by Sir Thomas Gresley's Arabian, called Bay Roan; out of Sir Walter Burdet's (afterwards Mr Burdet's) Vixen, which was purchased of Mr Coke" [Pick 1:72]. Both sources agree that Sir Thomas Gresley's bay Arabian was called Bay Roan.
