Princess Road was once known as Alexandra Road.
Alexandra Road was laid out about 1860 and aimed at a better class of clientelle.
Quite uniquely in Kilburn, this aim came to pass. By 1871, Alexandra Road saw half of its houses employing servants. This is contrasted with Granville Road, just one street south which became one of the poorest streets of nineteenth century Kilburn Park.
In the late nineteenth century, it was renamed Princess Road.
