The GSB [1:14] states that Young Bald Peg (YBP) is sired by Leedes Arabian (LA), but also says she is owned by Sir Ralph Milbanke, but research has shown Milbanke's horse was by Burford Bull out of a mare referred to as Oglethorpe's Royal Mare. Furthermore the GSB [1:3] says "Some accounts make Y. Bald Peg as by Spanker". Several different horses were probably named Bald Peg and YBP in the early years of the thoroughbred, so there were probably YBPs by LA and Spanker. Given the respective foaling dates:- Spanker (1670c), LA (1680c) and YBP (1681c) it is more likely this YBP is by Spanker; however, given the lack of certainty Pedigree Query continues to follow the main GSB entry.
