Thanks again Janet. All such hints and tips are invaluable.

I watched WDYTYA the other night - the Annie Lennox episode. I found that there were a lot of parallels in her relative Janet/Jessie's story with Fanny. I guess the local Poor House's Board of Guardians may have put Fanny to work somewhere - until she was "no longer required" by her employer. Maybe it was then that she turned to prostitution - at 18 years-old. Who knows, but it is a feasible explanation for her missing years.
