Three year old racing like the Derbies became really important with the demise of heat racing in England in the 1840s and really didn’t become that important in the US until the 1870s. The Byerley Turk line is famous for being slow maturing. It survived as a sire line only in France for a couple of human generations, IIRC–and it was also rather famous for stamina which goes along with slow maturation. When I say stamina, I’m talking about races that are from 2 to 3 1/2 miles long and longer. Bonne Cause and the sire of her son Bonne Nuit were both French bred, each from one of the two surviving Byerley Turk lines, In the end, both of their lines go back to the Herod line from Woodpecker, and I seem to recall that both of the founders of those lines were brothers out of the Alexander Mare of 1790.
Manni, in the early days of the TB, mares were rarely named, usually only if they raced themselves. They were considered of value only as the conduit for the male’s progeny. In Gonzales’s pedigree, he traces back to a daughter of the Byerley Turk (Byerley Turk Mare) who was out of a mare by Bustler (Bustler Mare). This is FF8.
The Alexander Mare was by Alexander (Eclipse son) out of a Highflyer Mare. Highflyer was by Herod. In her case, going back there are four generations of unnamed mares before you finally find one who has a name. Makes it really hard to keep track of pedigrees when there are many mares without names and known by only by their sire who, of course, could have had many, many daughters. For Instance, there are ten Byerley Turk Mares that made into the GSB, and not one of their dams had a name.
