http://prov.vic.gov.au/index_search?searchid=54Robert died in 1912 and only mentions his youngest son Alexander in his Will and leaves him some leasehold land consisting of 114 acres called Woodland Farm. Did Alexander marry?
Wilhelmina/Williamina's will has also been digitised.
Only mentions spinster dau Mary who I have probably listed as May Ethel on the electoral roll. One listing has May and another Mary Ethel.
So there doesn't seem to be any
GUNN descendants in St Arnaud in 1949 as Alexander died in 1939 at Fitzroy.
