For the death of Elizabeth Wilkinson the one registered Houghton 1896 age 64 should be the one.
The memorial says she is 64 it's off by 3 years since she was baptised 18 January 1829 at Barnard Castle, daughter of Thomas and Margery.
I have been trying to find anything that is further proof such as marriages with either a brother or a sister as a witness. Nothing so far.
I am going back to the 1851 census with Jonathan 17 and Margaret 15 living with Jonathan and Esther.
Margaret 15 would be Jonathan's sister she was baptised Pittington 22 July 1838.

Since William Robinson and Mary Wilkinson did not marry each other per the Record Office, it makes the William Robinson 1845 with mother's maiden name Burrell and Thomas 1848 with mother's maiden name Burrell puzzling.
It would be expensive but it would be nice to know who they have Mary Wilkinson married 1843 reg. Stockton.

When it comes to naming the children of Matthew and Mary Wilkinson nee Burrell - first daughter Dorothy - for her mother, second daughter Mary either for Mary or Matthew's mother, first son Jonathan for his father, then Ann, Margaret and Isabella seem to be Burrell family names, Mary had sisters with those names.
