Oldest Living Thoroughbred Tells All. 71 years ago, in March of 1941, old Merrick died. Merrick was more of a symbol of Thoroughbred greatness than an actual great Thoroughbred. His accomplishments were modest but consistent, and he lived until he was 38 years old, and he is the center of one of the great stories of horse-owner devotion. He was foaled in 1903 on a farm near Sacramento, California, and he had a few owners before Lexington pinhooker J. Cal Milam bought him in 1906.
