Regina's husband changed his name
This item ran in The London Gazette on January 17, 1947.
Scott, Ernest Arthur (formerly Ernst Schoenwald); Germany; Manager; 6, Aldridge Road Villas, London, W.n. 7 November, 1946
That would be Regina's husband. As foreshadowed by the crossouts in the registry record, Ernst Schoenwald officially changed his name to Ernest Arthur Scott.
So Gina's new name will be Regina Scott, which I am looking for in Google but everything is about the romance novelist who goes by that name.
