Antionia, I had the same problem when I started WikiTree a few years ago. My ancestry is incredible and I knew that, but these experts around the world can help you with Swedes emigrating to down under. Our family emigrated to the colonies when England cost of living went >35% with rotating strikes. We were first supposed to go to South Africa in 1975, Australia in 1976; then Mum and Dad backed out, finally we ended up here in Vegreville, Alberta, Canada as imported "knowledge workers" on the 22nd of February 1977; 22/2/77; today is my milestone birthday February 7, 1964; 7/2/74?; we lived at 72 Fleet Lane, Queensbury, Bradford 13 or Halifax 6, England. It is now all the same place. We were not allowed to bring any money from England; gave everything away and started again. Just ask people from your area in question; there are records of everything and that is what we are good at; some of these WT experts enjoy fixing our problems!
They can dig. I have met some incredible people working on Great Grandmother's profile; she was born in Barbados but my Grandad's dad is a BRICK WALL :(
