No, nothing up close, but there are some wonderful old lines, many pinto, and I believe almost every horse you have goes back to Rowdy, and your stallion has Falabella in the mix as well.
I printed out your AMHA pedigrees on all your horses, and at the bottom of each pedigree are the Show Results for all the horses with Show Records with the AMHA. Lots of nice old lines that are well known!
One of your girls is only registered AMHR, which only gives a few generations, and you have to go through many pedigrees to actually get a complete picture, and most of those go back to the AMHA at some point.
But you have some wonderful lines, and several pinto lines running through, so the "genes" may well be there -- even if not visually!
