We just don't know with what we have been told. We have been told that "Grandmother had a will where everything was left to him and when he died everything was to be sold and divided among 4 Grandchildren." This suggests some sort of testamentary provision for the grandchildren by the Grandmother.
This suggests that 2nd wife simply prepared a deed, and told the grandfather to sign it.
