Betty Leedes was also the dam of the unraced, but successful sire, Bartlett's or Bleeding Childers who was also by the Darley Arabian.

[8] Although the Duke received many offers for the colt, including one to pay for the horse's weight in gold, he remained the animal's owner throughout his life.

[9] This was claimed to make Flying Childers the only horse on record as having matched the top speed of the unbeaten Eclipse.

[8] Flying Childers stood as a private stallion at the Duke's Chatsworth estate in Derbyshire, until his death in 1741 at age 26.

Blaze was especially important, producing Sampson (his descendant Messenger is the founding sire of the Standardbred and very important in the Tennessee Walking Horse), Scrub, Childers (owned by John Tayloe II of Mount Airy Stud), and Shales (founding sire of the Norfolk Roadster, great influence on the Hackney).

[9] Such was the horse's fame that pubs were named after him, including at Bessacarr in his home town Doncaster, South Yorkshire, Stanton in Peak, Derbyshire, and Kirby Bellars, Leicestershire.
