The History of the Racing Calendar and Stud-Book says " When Messrs Tattersall dispersed the Royal Stud at Hampton Court on October 25th, 1837, amongst the lots was a bay filly foal, by The Colonel (a St Leger winner), out of a grey Arabian mare of the purest caste, which had been presented by the Imaun of Muscat to King William IV. This foal was bought by the elder Sir Tatton Sykes for 76 guineas, Pocahontas, also then a foal, fetching fourteen guineas less". It is said that The Imam transported the Grey Arabian Mare a great distance in order to present such a fine example of her race to the King.
