Alcock Arabian (Pelhams Grey Arab) Said to have been imported by Sir Robert Sutton from Constantinople, which would date him to the first decade of the 18th century, but the source is questionable, and the thoroughbred historian C.M. Prior was unable to find a date of importation. He may, in fact, have been a son of the Curwen Bay Barb and out of Sir John Parsons Old Wen mare (sister to Clumsy) by (Old) Hautboy - D-Arcy Pet Mare (possibly by D-Arcy White Turk) - Sedbury Royal mare (Family 11). The GSB states the Wen mare produced a colt from the Curwen Bay Barb. Further, in pedigrees of the Alcock Arabians famous racing and sire son, (Old/Portmores) Crab, the Alcock Arabian is also credited with siring (Ancaster) Gentleman (1723) and (Wynns) Spot. Wynns Spot, bred by Charles Pelham of Lincolnshire, who also bred Crab, is listed in the GSB as being by a son of the Curwen Bay Barb. Crab, the most significant of the Alcock Arabians offspring, was foaled in 1722 and bred by Pelham. A daughter, the grey Alcock Arabian mare, produced three good racehorses who were also sires, the dun or grey Dismal (1733), (Duttons) Whitefoot (1734) and Trifle (1738). If the Alcock Arabian was in fact a son of the Curwen Bay Barb, both Crab and the Alcock Arabian mare were closely inbred, the mare being out of a daughter of the Curwen Bay Barb, and Crab being out of a grandaughter of his. The Alcock Arabian was acquired by Peregrine Bertie, (2nd) Duke of Ancaster, in 1722 from a Mr. Alcock, who also had a stud in Lincolnshire.
