The Dunbrody was a three-masted barque built in Quebec in 1845 by Thomas Hamilton Oliver for the Graves family, merchants from New Ross in Wexford.
She operated primarily as a cargo vessel, carrying timber and guano to Ireland.
She was fitted with bunks and between April and September from 1845 to 1851, she carried passengers on the outward leg to North America.
In 1874, while travelling from Cardiff to Quebec, she ran aground in the Saint Lawrence River.
She was bought by a salvage company, repaired and sold again but in 1875 she foundered on the Labrador coast and was lost.
