Helen Fife, other name Chisholm, did indeed die in Dundee in 1872, age said to be 61. It would be worth taking a look at that death certificate. I only looked for deaths plus or minus two years, and Helen was baptised in 1808 so would have been 64 or 65 in 1872 and wouldn't have shown up in my search.
I tried to have a look at the Dundee Howff burial records, which usually give a bit of extra information, for example, where the deceased was born if not in Dundee, but my antivirus went crazy and warned me not to proceed because its security certificate has expired, and Firefox would not let me access it at all.
