No.

I have searched and have few to choose from but none of them look like they could be her.

I put 1898 -1901 in as a search criteria because she wasn't deceased on Janet's marriage in 1898 but on John McMillan's death certificate his status is 'Widower of Mary Duffy'. So I assumed it was between those dates but none of them looked likely so I widened my search to the last census I found her on 1891 just in case.

I now have to have a good look at all of them before I spend anymore credits.
