Stream Lion is a mare well known for producing event horses, including four of Bruce Davidson's top mounts.
Patricia Nicholson, of Kells, Co.Meath, Ireland, first bought Lady Luck, a mare by the Irish Draught stallion Laughton, from a nearby farm.
Stream Lion was ridden by Nicholson's daughter before being handed off to Peter Charles as a show jumper.
Her first foal was the 1982 Rennies Boy gelding, named Rebel Lion, who was ridden on the amateur event circuit in Ireland by the Co Kildare rider Donal McKenna.
Her four sons ridden by Davidson have had excellent careers at the highest level of eventing.
