Four of his clients were housewives who had never left Australia before and who, under trance, had come up with all sorts of details, and names of people and places,. They were taken to Western European countries where they said they had been living in the 18th and 19th century. Prior to their arrival, in 1983, Ramster and local historians searched archives, looking for and finding the names given in Australia.

She described various details in England that appeared correct when they were then researched, such as the location of stepping stones.

The investigation of the McDonald case was witnessed throughout by Dr. Basil Cottle of Bristol University. Peter Ramster's research has almost completely been ignored by the scientific community,
