Sorry ... sloped off to Lidl, came back with sweeties and forgot I'd posted

So if I could go back and meet her again, I would give her a hug.
Aww, that's lovely. I guess I made a HUGE assumption when I picked a great-grandmother, because mine died before I was one, so I've never had/met mine.... she's just data picked from newspapers and censuses to me.
I think yours gets "Best Answer" ..... even before I've read the rest.
A copy of Bradshaw's Descriptive Railway Hand-Book of Great Britain and Ireland!
Maybe the 1870 edition, Section 1 Kent, Sussex, Hants, Dorset, Devon, the Channel Islands, and the Isle of Wight?
Or maybe the 1860 version to cover Somerset and Dorset?
Ah, a good practical gift, but if you took it from "now" they'd probably bin it as it'd look a bit shabby

A pair of Bootlaces as she was fined 60 shillings in 1902 for stealing a pair 
Awww... what a strange thing to steal, unless you haven't got any of course!
Mind you, being in court that day might've caused her to have a conversation on the bus with somebody that lead to her meeting her future husband... and if she'd not been to court, she'd have done different things that day - and had different conversations other days!
A family tree of her descendants in a book
Oh I think you'd definitely get arrested by the Time Travel Police for that one!!!

The only photo I have of one of my great grandmother's is of a round, laughing woman. I think she might have had a sweet tooth and would most appreciate a big bag of special chocolates 
mmm chocolate. The gift you can rarely get wrong!
... give her some advice, have all of your 3 husbands and 1 lover cremated instead of burying them, so that they couldn't be exhumed and get her sentenced to death ...
Oh dear. Burial was so "the norm" back then wasn't it. Her undoing.
I'm intrigued as to whether you knew this story/the details before you started doing family history. Whether it's always been known/in full/openly, or if it was a small rumour that you really had to look for
