It seems that a married woman with a German/Danish surname gave birth out of wedlock in 1919 to a little boy, giving her maiden name and not naming the father on the birth certificate: presumably all as the result of a war-time affair. (The husband was English, not German, but had taken the surname of a Danish uncle whom he lived with in Liverpool as his father died a few weeks after his birth.) Is this a probable enough chain of events to encourage us to think we have identified the mother? (German name - war time affair - maiden name given.) The baby on the birth certificate had two Xtn names, and the person we think he was had the same two Xtn names, but on his death certificate many years later, the birth date is one day different from on the birth certificate. In 1919, were adopted boys given different Xtn names, or did they keep their birth names and only get an adoptive surname?
