Hi Di
I dont know who Hannah is yet but she could be connected to my tree. I have taken a look at both the census' you mentioned and will look at my tree again. I dont think she is the child you found on the IGI as on the 61 census, there is another Hannah Cutts with her parents; Matthew & Ann, as well as the nurse child Hannah with your Sandersons.
My Matthew and his wife Faith, didnt name any of their children Matthew but they did have a few sons that would be old enough to have a daughter in 1857/8.
If I find a connection, I will send you a message
