Old Sorrel Old Sorrel, sometimes known as The Old Sorrel, (1915–1945) was a Quarter Horse stallion who was the foundation of the King Ranch linebreeding program for Quarter Horses, and the cornerstone of the King Ranch horse breeding program.
Rancho Estelle Rancho Estelle was the home of James Sublett, one of the first large-scale farmers in the Rio Grande valley of Texas, within what is now Big Bend National Park. Prior to founding the ranch, Sublett and his partner, Clyde Buttrill, farmed the bottomlands along the river in the area of what is now known as Castolon or La Harmonia, downstream from the later ranch. After the partnership with Buttrill broke up, Sublett bought four sections of land, initially calling it Grand Canyon Farms, and later Rancho Estelle.
