Thank you both for your input.
Trishanne you are very clever. I hadn't noticed the name above the shop. The name may relate to my great grandparents, but I think the timing is wrong.
From what I can work out they were in the area from about 1892, when my grandmother was born in Ballarat and 1898 when my great aunt was born in Melbourne. A great uncle was born in Balmain in 1896.
By the 1900's they were in Tasmania. I wonder if I have missed another Vincent coming to Australia.
Oh for a time machine to go back and find out who they were.
