Thanks guys! That is amazing!
Since the hints from Sue I had been looking into a few things. I had come up with Thomas, born in 1850 as well. It seems he may have married Agnes Smith, with whom he had a child (Thomas, who died aged about 1). I think that Agnes was the wife that died aged 36.
Then I had thought that he had perhaps married Mary Jane (transcribed incorrectly as Mary Louisa, the mother of the boys?). I did not notice the Mary Jane Milbank. Is it possible he had 3 ladies on the go? Or perhaps there is more than one Thomas.
The electoral rolls seem to point towards Mary Jane and Thomas being the people who died in 1927 and 1932.
The Mary Louisa Young who was born in 1862 appears to have married Bruce Gunn, according to the Tas archives.
Are the Tasmanian Heritage Archives likely to have been mis-transcribed? I think Louisa and Jane are not similar names though!
I am very confused now! I very much appreciate the time you guys have given to help me out. Thank you.

Edit: Bruce Gunn appears to have been alive and well in the 1900s, however a Bruce Gunn married a Mary Ann Miller in 1900.
How big was Tassie at that time? Is it likely that there were all these people with the same names in Launceston, or would it be a reasonably assumption that they are the same people?
