Hi Castana
A few of us have stuck with you through thick and thin with your search. Unfortunately, Jennifer is away for a couple of weeks, so I think it might be left to me to respond.
First of all we had a John Seymour born Newbiggin circa 1876 with a father John, a coal miner, who married in Failsworth. We also had his WW1 service record which showed a number of anomalies.
Second, you then suggested (from info from relatives) that he might have changed his name (no proof from where they got this info).
Jora then found a possible John Richardson,b.Newbiggin at roughly the same time but she didn't give the refs, so I went in and searched and found a family, with an Alexander Richardson as head, who had a son,John, b Newbiggin. I gave the refs and also gave you the refs to a birth registration and also followed the family and suggested that there might have been a second marriage.
You then found a possible match for this John Richardson on the 1911 and have somehow 'leaped' him from Gosforth to 1913 in Failsworth as John Seymour, father John, coal miner, on a marriage registration. Also a WW1 record of the same John Seymour - who apppeared to go AWOL after the death of his wife.
I still am unsure how these two people are the same man. Have you followed up the John Richardson, in Gosforth in 1911, to find if he married and died in the NE or elsewhere and if he had a WW1 record?
Sorry to be a bit of a wet blanket but I think you're still miles from proving a connection.
I think you will have to go through the same tests for John Thomas Ritchie.
