Quamina was a carpenter who lived and worked on the "Success" plantation in
Demerara. According to da Costa, Quamina was African-born (originated from the
Akan ethnic group in modern-day
Ghana), most likely from the
Fante subgroup. He and his mother were sold into slavery when he was a child. His mother died on a plantation in 1817. In some source material, he is surnamed Gladstone, as the enslaved adopted surnames of their masters by convention.
Sir John Gladstone, who had never set foot on his plantation, had acquired half share in the plantation in 1812 through mortgage default; he acquired the remaining half four years later. He attended services at the Bethel Chapel of the
London Missionary Society on neighbouring Le Resouvenir plantation when the chapel opened in 1808. As was witnessed in a letter he wrote to the LMS, he was persuaded to attend the recently opened church by the person who he served as apprentice. his replacement
John Smith was equally impressed by Quamina's qualities. Quamina became Smith's personal favourite, and was highly trusted by John Smith and his wife, Jane. According to da Costa, he was a "loyal, well-behaved, trustworthy and pious deacon." He brought news of the congregation members on a day-to-day basis, and was always consulted about the affairs of any member. Quamina had many wives, but he cohabited for twenty years with Peggy, a
free woman. As was common with other slaves, he had been harshly treated and humiliated by his masters and once was beaten badly and incapacitated for six weeks. He was frequently forced to work, thus missing religious services. In 1822, when Peggy was taken seriously ill, he was forced to work all day, every day, and was not allowed any time off to look after her. One evening, he returned to find her dead. == The revolt ==
