“Resolved that the application of John Alexander and Co dated 31st ultimo for permission to name the New Streets leading from Northumberland Street to Dover Street as under: the one next to the Shankill Road, Westmoreland Street, the one adjoining St Luke’s Church - Cumberland Street and the street leading from Divis Street to Coates’ Street - Hastings Street be granted” 2nd August 1865. The Belfast And Province Of Ulster Directory 1877 refers to Cumberland Street intersecting under the street name Carlow Street. This may refer to a Duke of Cumberland. Clerkin in his book on Dublin Street Names states that Cumberland Street North/South were called after William Augustus (1721-65) and that Cumberland Street South was already in existence on a map in 1756. The time line for Cumberland Street Belfast would suggest a later Duke, Prince Ernest Augustus (1771–1851) (later King of Hanover), the fifth son and eighth child of King George III of the United Kingdom and King of Hanover. The Dukedom became a double dukedom in 1799.
