Conversation sparked by Ruth's talk turned to the problems that arise when the name of a street or a property, or even a whole town, has been changed. Fortunately Kerry Raymond and David Horton have made their (very extensive) work collecting and organising examples of this freely available at the part of their ChapelHill website called Renamed Places in Queensland http://www.chapelhill.homeip.net/FamilyHistory/Other/Renamed-Places-in-Queensland.html
This is just the place to look if your ancestors lived in one of the 14 Francis Streets scattered across the city that were renamed in the late 1930s to avoid confusion.
