OK I have reviewed the data from the two links on FindMyPast (signed up for a 7 day free trial, which I will have to remember to cancel so that I don't get hit with a £200 cost, as I already have a paid MyHeritage subscription).
These links show a single man, born in Liskeard, with a birth, given stated age on the two differently dated documents of around Sep/Oct 1871. Not sure if this is the right one, who married Emmeline/Emma in 1898, but still looking and going back to the earlier screenshots.
Thank you for the help so far.
