Actually... she go's back to the "big boys" on the QH side and some pretty famous TB's as well. Most of them were built for speed, a few halters and lots of western (speed). I don't know much about paints... but here's my take:
Leo takes you to Joe Reed who is a hall of famer. He was an influential sire in the early days. Rugged Lark was a descendent of Joe Reed. You also have King (P-234) also a hall of famer and influential sire. He was the sire of Poco Bueno. Doc Bar is another hall of famer, he is also a grandson to Three Bars. You also have Lukes Mcluke. Top Bracket is out of Top Deck, wich will lead you to Man O' War and Fair Play. Sugar Band will take you to Peter McCue which get's you to
Steel Dust who is one of the foundation stallions for the breed. Traveler is another legend that is worth mentioning.
Your don't have any of the newer champions but you have a lot of old blood...
Now as far as conformation go's... I can tell you she's a gorgeous mare... but I don't have the "eye" to spot the "bad" so I'll leave that to the pro's...
