Thanks for the reply.
I would love you to dig it up if you can- great!
The Yarwoods continued mining here too. Some went to Broken Hill as well. Two of Annie's older brothers- John Thomas Yarwood and George Henry Yarwood were killed in mining accidents as was her great nephew in 1938 in Bendigo. It was a dangerous occupation!
Let me know if you can find the postcard. I will send you my email address,
