Reporting back, as promised. First, I must say a big thank you to everyone who has contributed to this search. We seem to have solved one of my brick walls, even if it has thrown up a few questions that will probably never be answered. It's two generations back from me, and I am, as far as I know, the oldest member of the family!
The marriage was in January 1918.gives his age as 37, which is correct.
He is using Andrew as a second name, which he did on the 1911 census.
Father's name is Andrew - which I knew, and the occupation of manufacturer is ok.(If it had specified what he manufactured, it would have nailed it!)
Interestingly, one of the witnesses is one of his cousins, who I already have on the tree, so that is another positive.
His residence at the time of marriage is 83 Lowth Road, Camberwell, which janan has already come up with from the electoral roll.
Occupation is given as staff sergt(?) in the Army. I have not been able to find any military documentation for him.
I have created a document, putting all the finds in date order - I may pursue the death of his daughter, but have not been able to find the reference to it. (2014?) There is a possible on the Find a Will site, so may just give that a try.
All in all, a very successful posting. I only looked him up on the 1939 as an afterthought. I had gone to the library to go through it for all the relatives I knew were still alive then, most of whom I met in my early years. I still have some to look up when I have the time.
Once again a big thank you to you all - one of these days I might try throwing my other brick wall in the mix. With information becoming more available, things are certainly coming to light that I never thought I would find!
Regards,
FS
