Thanks for your work here. I think I've addressed all of your corrections. Only for one do I think the transcribed is more likely and suggest a surname note instead. On another, I see an extra letter and have modified to Mackey, although it could also be Mackay if the 'a' isn't closed. You reference finding him in 1891. These are both on page 2.
If you want to link to anyone in 1891 in Melbourne town or Melbourne & Brompton Gore, I transcribed these a few years back in Automated Genealogy: http://automatedgenealogy.com/census91/
