Cora,
I don't know whether Thomas William Hughes is deceased as the death records I have access to are either incomplete or don't go far enough into the 1980's to be sure. The last business directory entry I had for him is in 1980 in Whittlesea. He would be in his 90's now if he is still alive but I am convinced that, if he is deceased, then he would have died in the same area of Victoria. I have tried searching the telephone directories for the Whittlesea area but nothing conclusive as yet.
Many thanks.
