Eastern Empire arrived at Port Adelaide, South Australia on 21st June 1864. Unfortunately, I've had difficulty finding a site where I can get into the original ships passenger list. ... I can usually manage to find a ships list when I have an arrival date, but for some reason I can't with the Eastern Empire - it's a puzzle.
I did notice a typed list for this ship somewhere, which had a Jane Cadzow & an Elizabeth Cadzow on it ... but it was worthless because it gave no details, not even their ages.
However, are these two names familiar to you?
