I've found Edward's death registration in 1909, jul-sept, St George Hanover Square district, which is where Edward and Sarah were living in 1901.

Sarah's death registration not in the partial index - yet. She may have stayed in that area, or perhaps she went to live with one of her children.

Back to Henry - ask if someone can do a parish look-up for his marriage in Banstead - you have the date already. It should tell you which parish he came from. Of course that doesn't mean he was born there - just living there at that time.

Have you found Henry's death - again someone with access to the Shalford parish registers at the County Records Office might be able to do a look-up for you. Hopefully a burial record would say how old Henry was. That's assuming he was buried in Shalford of course.

Don't know if this helps.
