Mary Spencer made the first batch of Gibralters in 1806. She lived at 56 Buffum Street and then moved to the head of Bryant Street according to Salem Historian Jim McAllister.Mary was part of the Spencer family which had come from England. She first sold her candy from the steps of the First Church. The candy became very popular and she was known to sell her wares from a wagon to neighboring towns.The Gibralters were also very popular with sailors, as they stayed fresh in all climates. This way they were introduced to the Far East, China, and the East Indies. Gilbraters can still be bought at Ye Olde Pepper Company on Derby St. in Salem.
