The name of this street comes from the Royal Family and in particular Prince Albert. "The name Saxe-Coburg-Gotha came into the British Royal Family in 1840 with the marriage of Queen Victoria to Prince Albert, son of Ernst, Duke of Saxe-Coburg & Gotha. Queen Victoria herself was the last monarch of the House of Hanover." (https://www.royal.uk/). The minutes of the Town Improvement Committee of Belfast Corporation on 28 August 1895 indicate the naming of two new streets off Roslyn Street and London Street: Gotha Street and Coburg Street.
