I am experiencing difficulty contacting the Australian Institute of Genealogical Studies via email, regarding my aunt Renee M. Knight who died in about 1978/79. They collected names from cemetaries which I searched and eventually found one for R.M. KNIGHT but no other details. This was in Marysville, Victoria. She lived in South Yarra, Melbourne, but there is no trace that I can find of her death being registered. I wonder whether anybody could help me to follow this up?
