Darley Arabian
Bartlett's Childers was foaled in 1716. Bred by Leonard Childers, he was a son of the Darley Arabian and Betty Leedes. He was a full-brother to the undefeated Flying Childers, but was never trained to race. It was once thought that Betty Leedes only produced Flying Childers and a foal that died young, but it is now strongly believed that she did produce another foal by the Darley Arabian (Bartlett's Childers). He was known as "Bleeding Childers" as he frequently bled from his nose. He was sold by Mr Bartlett of Nuttle Court, near Masham, Yorkshire.
