Indian Skimmer - top class filly trained by Henry Cecil, won 6 Group 1 races 1987-1989 to earn a Timeform rating of 133, the same mark as her illustrious contemporary Miesque.
Killingholme Clay....named after well errrrr, Killingholme Clay, dug in North Lincolnshire not far from a place that gave it's name to a decent horse called Glanford Brigg. I'll be up that way tomorrow.
Vanroy....poor performer from back in the 90s, though I'm sure there was a decent Vanroy in the sixties owned by a woman (Mrs. B Mountain???) who put "roy" at the and of all her horses' names. Another guess is that Walter Nightingall trained for her.
