London burials

[Sumar]

Hello
I would be grateful if anyone could help me.
For many years I have been looking for the death of Amelia wife of Joseph Taylor.
She was living in Hitchin, Hertfordshire when the 1851 & 1861 census was taken.
In 1861 she was 41 years old living with husband Joseph a Drover. She had 4 living children the youngest being only 1 month old.
In 1871 her widowed husband was at a Beer House & Common Lodging house in Hitchin - Drover out of work.
I can only find her youngest child now living with Joseph's sister.
Amelia was the daughter of George Curtis a Farmer. I do not know where he lived.
I believe Drover's wives moved around with their husbands from cattle market to cattle market and wondered if she died on route. There are no Hitchin deaths or burials for Amelia or her children.
As the GRO Index does not give age of deaths for the following 5 entries I am unable to rule them out. The 6th Amelia was the correct age but was she wife of Joseph Taylor, Drover?
