MsSinclair on Family Tree Circles

Looking for James Crighton Sinclair 1921 - 2008 or thereabouts. Possibly born or lived in South Australia (maybe Mt Gambia) and passed away in Victoria. Married to Dorothy Sinclair DOB unknown DOD early 2002, possibly January. Lived in Victoria and Tasmania.

Mostly both resided in Blackburn, Victoria Australia.

Would be especially interested in the parents of both of these relatives and their occupations.
