Thank you, Jen.
It is indeed persistence. I think this one has had all of us totally gripped (obsessed?)
Davy, yes, it won't be Martha junior. Is there another Martha somewhere in the family? It could all be a fantastic coincidence, but then what happened to the widowed Martha after Jacob died?
What we do know is that a Martha Coulthard married a James Brown in 1918. Which may be one coincidence too many? Because there weren't lots and lots of people with that name.
Unless someone has a brainwave, it may come down to getting that marriage certificate.
The other thing is - if it is your Martha, then either she was a bigamist, or William Turner died before 1913!

It all makes total sense John
William dies or leaves pre 1913. Martha marries Jacob who is now stepfather to my GF William who's only ten year old so when he says his father dies in WW1 then that fits. Martha then marries James Brown after the war and later on 1931 Martha jnr is living with them as Martha Bell as she married Louis Bell.
If Jacob was a miner then that would follow the story of my GF saying he had to go down the mines
