I've managed to trace a lot of my family tree using scotlands people however I have a great great aunt who moved at some point after 1911 from Scotland to England, she was a matron at a London hospital probably during the second world war, and retired to a village in Essex before she died around 1998. I know she had a son but I've not been able to find her marriage certificate on Scotlands people or ancestry people therefore I don't know her married name and I've not been able to find a death notice either - could anyone tell me where else i could look?
