Bartlett's Childers stood in
Masham,
Yorkshire. Through his success as a
stallion he showed breeders that unraced horses were capable of siring top racehorses. He became
champion sire in 1742. His progeny included Smales's Childers, Grey Childers, Squirt, Coughing Polly and Hartley's Little Mare. Squirt was the sire of
Marske and Syphon. Hartley's Little mare was the
dam of a number of top horses including Blank (who also became a champion sire) and Shakespear. Marske sired the undefeated racehorse
Eclipse. Through Eclipse, his is the dominant sire line of thoroughbreds in modern times. ==Sire line tree==
