Hi Trevor,
Thank you very much for the post.
I have him on a 1891,1901 and 1911 Census and I also have his marriage and death. I have tried to use the census below as a starting point to find him:
1891 4147/27/47
2 Clarendon Street Southwick Durham
John Clark 40 yrs limestone quarryman b Sunderland
Harriet 38 yrs b Darlington
Thomas L 16 yrs. ironworks labourer
Jonathan 14 yrs. -do-
Ellen 12 yrs
Morgan 7 yrs
Margaret 4 yrs
John 2yrs
Robert 1 month b Southwick
I have found a birth that could be his sister Ellen (Eleanor) in 1 Nov 1883 - Cockerton, Darlington.
Again,Jonathan (John) I have found a birth record that may be him. I believe that this could be a birth for Morgan
https://familysearch.org/pal:/MM9.1.1/2XLF-6YXA relative of mine had the image on something similar to cardboard and a while ago got it made into this. The cardboard image wasn't in the best condition however on my next visit I will get a copy of the original because perhaps a better version could be made.
She was reading a newspaper article recently and thought that this could be Morgan so I am trying to establish if it may be him in the photograph by trying to find out about his uniform. She would like to know more about him. She had a really strong feeling about this so I thought it couldn't be wrong to have a little look

This is the article

The caption underneath the photographThe sergeants of the 11th Battalion The Royal Inniskilling Fusiliers at Bramshot in 1915. Could this photo contain the image Sgt David Blakey, from Felling, Tyneside, who’s body has been found 98 years after his death in France. I do hope they find relatives for Sgt David Blakey.
Much appreciated,
Fran
