At the time the family was living in Cromwell Place in the small market town but by 1871, after the death of her father, Sarah and her mother had moved to Priory Road. Both were listed as annuitants.
And then she goes to London. Why? No idea, but she plainly found something to interest her as she married Christopher Stuart Toll in Islington on 24th June 1875. Mr Toll was a Stevenage boy and they seemed to return to the Hertfordshire town as Sarah sadly died there, at the age of just 26, in 1877. There were no children of the marriage.
Persistent as I am, I have found Chris Toll in 1901; still in Stevenage, he was listed as a Relieving Officer. Any clues??
