Thanks Hugh,
You found information that took me ages to find

For a long time I thought that record, you have also unearthed was the JW Shepherd I was looking for and it gave me more leads with respect to his place of residence, maybe birth and his age.
However, on the marr cert he is listed as sergeant East Yorks reg, Fulford barracks. This is also this is confirmed on the cert for birth of his 1st son (Fredrick) in 1916. He is listed as a army gym instructor also. He survived the war and was a home guard and rifle range warden (so my mum tells me in WW2).
Incidentally, paid some money for someone to search the army records but it did not turn up anything concrete.
I am hoping that of his 3 boys some of their offspring will know the family history. The problem with searching census is I have a rough age (b 1890) and I know his fathers name...but I lack any support info like place or other family members...consequentially there are several possible (maybe as many as 8-10) candidates.
Thanks again
Jon
Thanks for your efforts though.
