Dam of Sister to Regulus (by Godolphin Arabian), through which the maternal line of the family continues, evolving into all branches, 11-a, 11-b, 11-c, 11-d, 11-e, 11-f and 11-g, of the family,

Dam of the great racehorse and sire Regulus (1745 King's Plates Winchester, Salisbury, Nottingham, Canterbury, Lewes, Lincoln and Newmarket, 1746 King's Plate Newmarket, and Champion Sire 1754, 1755, 1756, 1757, 1761, 1763, 1765 and 1766)

Early published, certified, pedigrees for Regulus omit the Snake (sire of Sister to Old Country Wench) cross as the dam of Grey Robinson, so it is very possible that the dam of Grey Robinson is not Sister to Old Country Wench but rather her dam, Grey Wilkes
