What is "sookera"

Sookera (18 May 1975 – 2004) was an American-bred Irish-trained Thoroughbred racehorse and broodmare. Racing only as a two-year-old in 1977, she won three times and finished second twice, from five races. After winning on her debut and finishing second on her next appearance, she recorded her first major success when defeating male opponents in the Chesham Stakes. She returned from a late summer break and finished second in the Moyglare Stud Stakes before winning the Group One Cheveley Park Stakes. Sookera never ran again but became a very successful broodmare. She produced several winners including So Factual and is the female-line ancestor of numerous major winners including Dansili, Leroidesanimaux, Banks Hill and Intercontinental.
