Lester Keith PIGGOTT, the famous English jockey, was of family which had origins, I believe (from a brief look at his biography in a bookshop some years ago), in Cheshire, probably around Congleton. He was born 5 Nov 1935, probably at or near Newbury, son of Keith & Iris PIGGOTT; and grandson of Ernest PIGGOTT (a Steeplechase jockey) by Margaret CANNON (from a Google.search). His father Keith was a jockey; his grandfather Ernest's brother was Charles PIGGOTT, Trainer. Lester married in 1961, Susan ARMSTRONG, by whom he had a daughter Maureen PIGGOTT(who marr William HAGGAS); & by one of his staff members, Anna LUDLOW, he had a son Jamie. Lester also fell foul of the law - he was imprisoned in 1987 after a conviction for a "white-collar" crime - tax evasion; he served 366 days of a 3 year sentence, & was stripped of his O.B.E. - but I do not see an immediate connection to the "Jack" PIGGOTT of California in 1903. However, there was a Massie HARPER, Licensee of the Lion & Swan Hotel, Congleton, ca 1890s, whose grandfather (un-named) was Lester PIGGOTT's gt-gt-grandfather (also un-named). In the English Census of 1881, at Nantwich, Cheshire, there was enumerated a family headed by Thomas PIGGOTT, Head, Marr, 51, Hotel Keeper, b Bartherton, Cheshire, with his wife Alice, 41, & 5 sons & a daur, incl John, 12, Charles, 6, & Ernest, 2. In the 1871, this same family were at Woore Hall, Salop (or perhaps instead Staffs), where Thomas was named Thomas Massie PIGGOTT, 41, Farmer, with wife Alice, 29, with 4 sons & a daur. The MASSIE connection here is probably significant. Ernest PIGGOTT married at Stockbridge, (Hants/Wilts), June qtr, 1903, to Margaret Kate CANNON, so his Sept qtr 1878 birth in Nantwich is not inconsistent with the above details. Thomas Massie PIGGOTT marr at Nantwich, Cheshire, March qtr 1862, Alice WOODWARD. In 1851, Thomas M. PIGGOTT, 21, was enumerated, with 2 sisters, res with their parents at Batherton Hall, Cheshire - George PIGGOTT, Farmer, 63, b Wisaston, Cheshire, & his wife Elizabeth, 63, b Wybunbury, Cheshire. So, it is quite possible that the "Jack" PIGGOTT of your query could have been the John PIGOTT, aged 2, with parents, 1871, & aged 12, ditto, in 1881, but not with widowed mother Alice in 1891 (at Crown Inn, High St, Nantwich, with family George, 28, Frederick, 27, Alice, 18, Charles, 16, & Ernest, 12), & at age 22, quite capable of looking after himself. And this possibility is further supported by the fact that Ernest PIGGOTT did win the Grand National Steeplechase in 1912, so perhaps by then he had already achieved the status of a "celebrated jockey."
