Thanks for the input. There is a possible 1851 census entry in Walker HO107 2411 106 5 but that says she was born in Ireland! The names do fit in though.
George Allan 38 Blacksmith
Helen wi 35
Eliza dau 13
Margret 11
David 9
Edward 7 all born Ireland
Matilda 8 months b Walker
I have spent hours at the FRC trawling through the books and could not find a birth in Tynemouth district which I believe covered Walker at that time. If she was born in Ireland that might explain it!
The spelling does vary and I have always looked for both.
Thanks for the help
