Was Dawson her maiden name? If not, what was it?
According to familysearch she married a Charles Donahue on 4/12/1942 in Repton, Derbyshire. Is this the same person?
I am starting to get a bit confused here. Did she then divorce Donahue and marry "Dawson"? If so where was that? Where die she die - Rhodesia or South Africa?
She would not have a South African Identity number of she was in Rhodesia.
