The origin of the village name is a matter of some controversy. According to local lore, the name, which was first referenced in 1817, could have had any one of three origins. Some speculate it is a reflection of the joyful experience of the first settlers in finding such a welcoming environs. Alternatively, it has been postulated that the community was named to commemorate a ship belonging to 17th-century pirate Peter Easton. Still others suggest the community was named by George Holbrook, a British Admiralty hydrographer. Holbrook surveyed Newman Sound in 1817 and sheltered in one of Happy Adventure's coves during a storm.
