Hello,
I am also a desendant, located in Melbourne, Australia.
Having only recently become interested in the family line, I thought you would be interested to know that I have an actual hand written small journal, written by Earnest munro {1910} telling the story of his wife, who apparently was one on the children. The journal detail the story of the fire, & the ongoing story from that point.
Surely it must relate to the same family!
FYI, my middle name is BRANDON, following the family line.
Cheers.
