Interesting that there is a constituency called "Belfast Victoria".
It was also used for a Stormont constituency from 1929 (FPTP in those days) and remained the name of a local government electoral area until 2011. One of the successors is now called Titanic: yes, the name refers to that Titanic.
Although the old Victoria DEA only included bits east of the river, whereas that Belfast Victoria constituency was made up of the bits of East Belfast north of the Newtownards Road (very working-class round Sydenham with ship-building as the main employer; more middle-class further east) but also hopped across the Lagan to take in the Docks and the nationalist New Lodge area.
