As for Fanny, she lived long enough to see the First Labour Government come to power in 1935, passing away in 1941, as New Zealand fought the Second World War. And it seems Fanny was not the only member of her family to sign the petition in 1893. Fanny's maiden name was Lawrence, and the signature immediately beneath hers is that of Mary Lawrence. I am guessing this was probably an unmarried sister. Time to do some some more family history research.

[Since first posting the above, a lively and fascinating discussion on Twitter has confirmed that I should have used the term 'suffragist' rather than 'suffragette'. In the interests of historical authenticity, I decided to allow the original wording to stand. Regardless of the correct terminology, it is nice to have an ancestor who stood on the right side of history.]
