So I made a diagram trying to map out the connections between my chosen books and this was the result:

It was very hard finding words to connect all of the books so I connected a few at a time with very broad words.

Then I factored in my research and found that there are a lot of indirect ways this information could relate, leading me to research what else was going on during those time periods. For example, The owner of The Wellington-Manawatu Railway Company could have been listening to pink noise at the same time as reading a news paper similar to the listener about the woman's’ vote being allowed and possibly redesigning his house to be more secure like it describes in the SAS guide. 

I wondered whether any of the directors signed a pension for woman’s vote and eventually found the names listed here http://nzetc.victoria.ac.nz/tm/scholarly/tei-Cyc01Cycl-t1-body-d4-d19-d2.html then I searched on this database https://nzhistory.govt.nz/politics/womens-suffrage/petition none of their names were there but it was an interesting find.

I went a bit further into the history and was shocked at “They warned that any disturbance of the ‘natural’ gender roles of men and women might have terrible consequences. The liquor industry, fearful that women would support growing demands for the prohibition of alcohol, lobbied sympathetic Members of Parliament and organised their own counter-petitions. “ - https://nzhistory.govt.nz/politics/womens-suffrage/brief-history well the liquor industry is just fine…

And I end with an art work from 1885 https://www.stuff.co.nz/the-press/christchurch-life/art-and-stage/visual-art/95742048/from-the-christchurch-art-gallerys-collection-among-the-sandhills
