My once in a lifetime horse Ruling Angel (she's back in Oz) was sired by Rancho Ruler, famous Australian racehorse. He was a top racehorse sire in the 90's, group 1 stakeswinner and sire of many many winners. My girl couldn't win a race to save herself, 11 starts for 7 lasts I think, never placed he he. Good thing she could jump like a deer!
Oh and another horse of mine was somewhat infamous, banned from two associations cos he was a nutjob and went off the deep end frequently, putting others around him in danger. Had to sell him eventually, only horse I have ever been glad to get rid of!
My gelding ain't famous (except for perhaps being the one they always suspect first of tearing down the wire), but his sire is the recently deceased GS Khochise+++//, grandsire the great Khemosabi++++//.
Pickles, and a pic of Khemo so you can see the feint resemblance of their facial markings, which I thought was cool carried over:
My horse has zippo pine bar , red sonny dee and poco bueno in his bloodlines. Also when he was a baby, he was second in the nation halter horse for paint. Now he's a western pleasure horse and has won greatly at paint and pinto worlds.
