We have done most of the family very successfully but completely stuck on my grandmother's line.
Her mother is an enigma - she remarried after my grandmother was born, my grandmother was put into a children's home, then we can find out nothing more about her mother. No death certificate, no further marriage, nothing.
Are there any records for emigrations?
Or do you have any other ideas about where she might have gone? This is in the 1930s/40s in County Durham if that helps.
Obviously this is not stopping us from taking the line back further, it's just a mystery.
