Johnson's Court off Grafton street. Can anyone tell me what type of street it was/is?

Johnson's Court is a small narrow street running between Grafton Street and Clarendon Street. At the moment it is the home to a number of mostly jewelery shops. You can just about see it on Google maps street view now. I don't know if it was part of the Jewish community. I always believed that the Jewish community were centered around the South Circular/Clanbril Street area.
