Hi Monica.
Thank you so much for your response.
Thank you for confirming about the Census, I did seem to find information regarding her parents and Brother and Sister.
I have looked on Scotlands People, which is a really helpful website. I managed to locate Mary's Death certificate where I was able to find out about her parents names and her brother.
I know she was a Nurse in Glasgow and lived in Park Circus Place and want to find out a bit more about that and have had so much help for so many kind people in relation to contacting certain organisations.
Once you start you cannot stop!!!

Thank you again.
