Where is Magistracy Street located?

Does anyone know the exact location of "Magistracy Street, Victoria Hong Kong" in 1840s? Also, who is J. Dos Anjos Xavier?

Forum: 

You could try the 1845 Map. I took a quick look and though I didn't see a 'Magistracy Street', there is a building marked 'Magistracy' above Hollywood Road on the site of Victoria Prison. So maybe somewhere around there?

Not sure about J. Dos Anjos Xavier. Any extra background you can give?
