 In 1791, Falconbridge was selected by the Anti-Slavery Society to sail to Sierra Leone with his wife Anna Maria; and his brother William, with the intent of reorganising the failed settlement of freed slaves in Granville Town, Sierra Leone.Unfortunately, his wife Anna Maria did not share his idealistic views about the settlement.The couple quarrelled; Falconbridge began to drink excessively, due to marital problems and ailing health and, it would seem, disenchantment with the Sierra Leone Company.
