Well this is fantastic news. I was out for the evening, came back to see pages of posts and such great posts. Well done John 
Still need to find what happened to William.
Johns research definatly fits with my grandads story all be it his stepdad.
Hopefully the 1910 death cert will finalise things
So much new information today though including confirming that Martha Jnr married Louis Bell which I wasn't sure on.
Excellent work everyone
