Pamphletboy;
That’s an interesting thought. My grandmother was born in Perth, we found the home on a previous journey but it was a while ago. We do have some record showing her birth date and address, not a certificate though. That would have been in the late 1800s time frame. Good idea, I’ll have to follow that up with research.
