Foundlings

The final episode of the British television series 'Long Lost Family', which helps close relatives who have lost touch to find one another again, dealt with the case of a foundling who was trying to find her birth mother. She had been left as a newborn baby on the doorstep of a flat in a tenement block in Grangemouth in Scotland in 1967. When she was a few months old a couple who already had two sons adopted her and she had a happy childhood, but when she was told the truth of the circumstances of her birth she wanted to try and find her birth mother. She was unsuccessful, and the programme drew a blank too (unusually but not surprisingly in this case). One thing that wasn't mentioned was when, how and by whom the baby's birth would have been registered. She spent the first weeks of her life at a local hospital so perhaps they took on the responsibility of registering the birth. It must be extremely distressing for the person to have neither parent identified on the birth certificate. And what name would she have been given before her adoption? Does anyone know what happens in these circumstances?
