Thank you so so so much to everyone who has posted :-)
Thanks to Stan's discovery of John Payne being wrongly transcribed on the birth records, the mystery may be solved!
Also thanks to Isobel for the extra information :-)
I have now found in all likelyhood the parents of John Thomas Payne, and have the information of his mother on the 1911 census, so now I need his father George Payne, who was born in 1989 in Sunderland :-)
Thank you so much for all your help, I am very grateful indeed! :-)
