Having researched my own family history (and many others), I am always interested in the lives of women in the 19th century. Domestic service played a large part many ordinary women's lives. My great-grandmother was a servant in "big house" a couple of streets away from where I live now.
In my own home I still have evidence of the importance of domestic servants - the servants bell - a device which was used to call servants to various parts of the house.
Fortunately, it no longer works, but I'm sure it was the bane of some poor girl's life in years gone by.
Don't try this at home!
I wonder if they really had to do this?
