Good work, Bryant, but I'd already checked this chap out and he died in 1917, if I remember rightly, in Egypt.
He was a good match.... for a while. And he had a really interesting family too, more's the pity.
I've found a Douglas Wood in Rickmansworth who was an apprentice boat builder that also looks interesting. The trade given on the birth certificate was Carpenter.
One thing I did forget to mention, is Douglas had a middle name of William. I only remembered when I'd been looking at the certificate again this afternoon. A quick check on the BMDs found a Douglas William Wood born 1895 in Watford. Although Ancestry didn't have a marriage match, I found one on Find My Past, where there's a marriage for a Douglas Wood to Elizabeth Atkins in 1919, Watford registration district.
Maybe that's a reason (if it is him) that Douglas and Jane weren't married and never married.
Best regards,
Sally
