Thank you all for your suggestions. With these in mind I will try and read this census entry again. Actually, the Agnes looks promising but I may be over-optimistic....!!
My mother's name is Mary, but, as her mother was also Mary, she has always been called Maisie, so I can imagine the fun people will have with that, in years to come.
Good luck with your searching.
