Firstly thank you one and all for your input. As I said in my post IF this is the lady I am looking for, her daughters, and son-in-laws would have had the money. As well as her sons IF they were still in Victoria.
Thanks jamjam, most likely my tree anyway.
I have been hunting for information relating to her death for years without success. These court events could well explain a few things for me. Time line, husband died suddenly 1871, everything was sold up to repay the loan his sister had made to him. and I mean EVERYTHING. The daughters were married by 1873, her parents dead, sisters' married and scattered. Her son's relocated to north Queensland.
When the tree was done for the 176 year family reunion (200 in 2022) it was stated that Fanny had died 1880 and was buried at Anakie. (assume Victoria as that was where the property was. Problem there is no death records to be found, no cemetery at Anakie Vic. and at Anakie Qld the cemetery records have been lost. Only graves with headstones appear in the 'new' record of burials.
Yes, she was born 1820, just out of Edinburgh, Scotland. Baptised at Gladsmuir. Her favourite sister was Elizabeth, even though Fanny was 53 she may well have had a breakdown. So I can understand her slip on names.
