His sire was Hickory Bill a TB and his dam was a Dr. Rose mare and I am pretty sure she was an un-registered TB. I'll double check and if she is not, I will correct myself.
Hickory Bill's not entered in the main body of the ASB, but he may have been JC-reg. for racing purposes only (names unpublished in the ASB). Ditto his dam. Second dam has a produce rcd., appendix ASB 7 recording her earlier foals. But the appendix was officially discontinued beginning w/ ASB 8. A handful of offspring of appendix mares did have produce of their own recorded in the main body of that and later vols., but I haven't found Lucretia M. and/or her foals among them.
Estimating Old Sorrel's degree of registered (TB), unregistered (TB), & unregistered 'Quarter type' blood is like trying to nail jello to a tree. Start w/ how much faith to place in the notarized affidavit from the son of his grandsire's (Peter McCue) breeder that P McC was actually by the unreg. Dan Tucker, but falsely registered w/ the JC as by Duke of the Highlands. Then scrutinize the unregistereds. (For starters, the commonly accepted pedigree for Jack Traveler doesn't even begin to pass muster by dates.) And the degree of TB blood in Steel Dust, Old Billy, et al. has been a matter of endless speculation, but little hard fact, for how many generations? Etc.
I don't recall Denhardt making any definitive statement re. the Dr. Rose mare in the King Ranch QH book, but at the moment I can't locate my copy.
