There were several horses named Crab who stood in the early part of the eighteenth century, causing confusion in the pedigrees of their descendants, especially as Lord Portmore owned three of them. Also Mr. Cheney referred to Old Crab as "the Earl of Portmore's Crab" in his Racing Calendars [Early Records, 35].

There were also at least two horses referred to as the Ancaster Arabian. One of them was the subject of a painting. "On a canvas 3 ft. by 2 ft. Seymour shows how the Duke of Bridgewater's bay horse, Hazard, beat the Duke of Ancaster's grey Arab, each horse carrying 9 stone." [British Sporting Artists, 74]

Seymour's picture must be of the following race taken from Baily's Racing Register:
Newmarket 1732 April 4th. Sweepstakes of 100gs each, for five yrs. old horses, 9st, 5 subs.

Bred by Mr. Routh [Early Records, 90], Ancaster Crab was probably sent to Virginia in 1737, where he stood at Secretary John Carter's "Shirley" in Charles City County. He appears in the pedigrees of Young Paul Jones (b.c. 1789) and Ridgely's Syphon (b.c. 1795).
