Your original info request had James Donald Gilmore MURDOCH. Some date bases will only search on first names & surname . Others will accept first and middle names. Sometimes you will get a 3rd name pop up with a search.

I searched for James Donald MURDOCH in the Aus electoral rolls for starters . Not many ( many Donald James MURDOCHs) Nothing promising , Checked Ancesterys UK out going passengers and the NAA immigration indexes with same result

Didn't consider that time well spent
