Golden Locks

"GOLDEN LOCKS, Got by Sir R Mostyn's or Bristol Grasshopper, son of Byerly Turk, her dam by Lord Bristol's Hog, of the Hautboy sort, grandam by Duc de Chartres' Hawker" [GSB1:10].

Gentleman

The General Stud Book is uncertain whether Gentleman is from Golden Locks or from her sister, and although it does mention an Alcock Arabian Mare, it doesn't specifically say that she was Gentleman's sister. "The Duke of Ancaster's gr c Gentleman, by The Alcock Arabian, foaled 1723. His colt Creeper, foaled 1733, by Cinnamon, and a f by Alcock's Arabian, were either out of this mare [Golden Locks] or her sister" [GSB1:10].

C M Prior speculates that Gentleman may be the grey colt of 1723 produced by the mare Virgin [Early Records:95]. However, Virgin's colt is unnamed and she is not shown to have had another foal by Alcock's Arabian [Early Records:87]. Prior does note that Gentleman's Sister produced a grey filly to Stumps in 1735 [Early Records:86]. His speculation is possibly prompted by the appearance of Gentleman in extracts from the Duke of Ancaster's Trial Book. Since both the Turf Register [Pick1:22] and the General Stud Book agree that Gentleman was from Golden Locks or Sister to Goldenlocks, it is probable that he was not bred by the Duke of Ancaster, but later purchased by him, and that he was not the unnamed son of Virgin.

Rib Mare

Although the General Stud Book is uncertain whether Gentleman's dam is Golden Locks or her sister, it is specific that Rib Mare decends from the sister to Gentleman's dam "RIB MARE, Her dam by the Wynn Arabian - Governor - Alcock Arabian - sister to Gentleman's dam, by Mostyn Grasshopper (son of Byerly Turk)" [GSB1:171; Sprightly:199; and Countess:63], from which it is apparent that the Alcock Arabian Mare and Gentleman are not full siblings, as later sources indicate. Since the Alcock Arabian Mare is also the daughter of either Golden Locks or her sister, she must be from the sister which is not Gentleman's dam.
