Hello, I will copy the details as I have them........
1871 Census,Houghton le Spring District, family number 15969.7
Houghton le Spring 1871 Census, Sunderland Street
William Kirtley, Head, married 71, Tailor, born Wolsingham, County Durham
Jane Kirtley, Wife, married, 69 born Durham City, Co Durham
Anthony Kirtley, son, 31, coalminer, born houghton le spring, co durham
George Kirtley, son, tailor, born houghton le spring, co durham
Margaret Kirtley, niece, 7, born, houghton le spring, co durham
Jane Kirtley, niece, 4, born, Pelton Fell County Durham.
It looks like she could have been living at her grandparents house ?
I have requested various birth certificates from the registrar, but they always come back, that the father isn't Anthony, so I conclude that her name on the birth certificate is not Jane, even tho on her marriage certificate, and death certificate she is "Jane".
The above census info, was from Durham records online
many thanks for searching - sandra
