Thank you all. I wonder how I could have missed those articles on Trove when I was searching for E E Brown. But I have to confess that it hadn't even occurred to me to look in Scotland
Milliepede, I did check the QLD index for a marriage and a death under a married name.
Kerri, I had found that listing in the QLD index. Unfortunately I can't afford to buy every certificate I'd like to see at $20.70 a time! I have 376 births, 239 deaths and 132 marriages in QLD, and it would cost $15,462.90 to see them all

I will look up the death certificate next time I am in the Scotland's People Centre, where for just £15 (the price of 10 Scottish certificates, or a little more than one QLD certificate, online) I can look at as many certificates as I can work through in a day.
