Hi!
I'm trying to trace any information about my great-grandmother. I know that she was born in August 1908 in St Pancras, London to French parents. She was one of 4 girls, although they weren't all full siblings. Their last known address was Warren Street. When war broke out, the parents went back to France, leaving all 4 girls in a convent.
I don't know which convent, and I can't find any trace of the other sisters.
Any advice?
