At least 3/4 Thoroughbred.
La Hernandez produced the full sisters Della Moore (the famous Cajun match racer) and Old Queenie. Old Queenie became the second dam of the clubfooted Flying Bob mare Queenie, the 1945 world champion racing Quarter Horse, while Della Moore’s first baby was the Joe Blair (TB) stallion Joe Reed, who founded the family that flowered through Joe Reed II, Leo and First Down Dash. Della Moore was then sold to Ott Adams, and produced Aloe, Grano De Oro, and Joe Moore, all by his great stallion Little Joe. These two daughters have had a huge, lasting influence on the breed.
