The StudBook, although silent as to the date of his birth, says he was a common country stallion in Lincolnshire until Partner was six years old - and we know from the same authority that Partner was foaled in 1718; we may therefore conclude that Jigg was a later foal than Basto, who, according to Whyte's History of the Turf, was a brown horse foaled in 1703.
The Stud-Book shows of what breed the royal mares really were: one of them, the dam of Dodsworth (who, though foaled in England, was a natural Barb), was a Barb mare; she was sold by the stud-master, after Charles II.'s death, for forty guineas, at twenty years old, when in foal by the Helmsley Turk.
There is not the least doubt that many of the animals named in the Stud-Book were foaled much earlier than the above dates, but we have no particulars as to time; and after all it is not of much consequence.
The Stud-Book is silent, and other authorities differ, as to the date of the importation of this celebrated Arab, some saying he came over in the year 1700, others that he arrived somewhat later; but we know from the Stud-Book that Manica (foaled in 1707), Aleppo (1711), Almanzor (1713), and Flying Childers (1715) were got by him, as also was Bartlett's Childers, a younger brother of Flying Childers.
Flying or Devonshire Childers, so called to distinguish him from other horses of the same name, was a bay horse of entirely Eastern blood, with a blaze in his face and four white feet, foaled in 1715.
