Snyder, Texas
Quo Vadis was foaled 1952 and bred by Ross Roberts of San Jon, New Mexico. She was a black mare, owned at the time of registration by Marianne Randals of Snyder, Texas. Both her sire and her dam's sire were products of the King Ranch linebreeding program, so Quo Vadis was descended from Old Sorrel twice. She also traced five times to Peter McCue as well as once to Traveler.
