Seth, born at New Mills in Derbyshire on April 6, 1863, had the distinction of riding five consecutive winners (his only mounts) on the second day of Pontefract’s Summer Meeting, July 6th, 1893.
The son of a cotton-weaver, he was apprenticed to Middleham trainer H Hall, and became a leading lightweight after riding his first winner in 1883.
He was badly hurt in a fall from Rigmarole at Leicester on November 16, 1898, but carried on riding until 1909.
Big wins during his career included 50/1 shot Veracity (Lincoln, 1888), Tyrant (Chester Cup, 1890), Golden Drop (November Handicap, 1893) and Georgie (Cambridgeshire, 1898). He also won the 1892 Ebor Handicap on Alice.
Seth soon spent the money that he had earned from his riding and was forced to seek work. He was employed first as a horse and cart driver then, his plight worsening, as a boot boy in a Stockport hotel.
It was here that he died, penniless, on August 22, 1926, aged 63
He was buried in New Mills Parish Church on August 29, 1926.
Seth's younger brother, James Arthur Chandley, was also a jockey. He was born in Stockport in 1870. He died in 1948.
