Sired by Triple Chick and out Trouble Fair, Boston Mac was bred by master breeder Reed Hill and foaled in 1968. He sold at the 1969 All American Yearling sale to Kathalyn Green, who sold him five months later to Jerry Wells.
He was the fastest qualifier in the 1970 All American trials earning a top triple AAA rating in the process.
Jerry sold a half interest to Frank Merrill in 1971 and they started showing him at the Gold Coast Circuit in 1972. He amassed 43 first place awards in the 43 times he was shown, placing Grand Champion 35 times and Reserve Grand Champion 8 times at some of the country’s most prestigious horse shows.
Frank broke him to a stock saddle and started riding him at horse shows, which resulted in his earning an ROM and becoming an AQHA Champion.
At that point Wells and Merrill started a breeding program and bred him to 132 mares. Subsequently Jerry decided to discontinue breeding and sold his interest to Frank’s father. In 1974, Frank’s father sold his half interest to Jerry’s brother Jim. Jim and Frank stood him at Windward Stud through the 1976 breeding season. Later in 1976, Frank sold his half interest back to Jerry and in 1978, Jerry and Jim syndicated Boston Mac.
Glenn Cantrell stock Boston Mac for two years after Jerry sold his place and later the stallion stood in Nebraska with Patricia Palmer.
