You have put that it is a fact that she was born in 1919, our research suggests 1918.
Where does the information for 1919 come from?
'late' does mean last known address.
rosie99 has said that there is a probable marriage for her in the same area as the newspaper mentions, according to the code in 1939. We cannot tell you that name - do you have access to Ancestry, F M P, or another pay site to look at the 1939?
