I have had no luck finding an Irish birth record for a lady who ended up in UK and where she died in 1984. She is in the 1939 register but we think was not married to the man she was living with and whose surname she used and gave to her only child. I cannot find any marriage record for them either in UK or Ireland or of him to anyone else.
The only hard information is her date of birth in 1907 and christian names. But no joy with searching the Irish birth records and filtering for that date/name.
She never returned to Ireland. I wonder what was done with birth records of mother and baby homes of the time? Were all births registered by the institutions? And so many adopted out, were they give a copy of some form of a birth certificate? Was it not a legal requirement for subsequent marriage?
