Hi Jen and Margp, I have tried every combination I can think of, but not the Electoral Register as I have no access and unable to visit Durham Records Office. I don't know the informant on Annie's death certificate as I have not received it yet. The date of birth for Alfred Ernest Tyson was 15th January, 1899 and he was baptised on 26th February, 1899. Annie and Alfred Ernest had three children the last one being born in 1936, so I am also awaiting that certificate to see if it gives Alfred Ernest's status as (deceased)
The reasons that the other two certificates were discounted Margp was that the on the one from Barrow in Furness, the place of birth differed and the informant of the death was named as sister which also didn't fit. The Sunderland one also was a misfit.
Many thanks for your interest
Doric
