Hi Anonymous Welcome to WikiTree.
We can probably help you if you give us just a little information about Margaret.
A date range of when you think she was born.
An idea of the location where she was born or lived.
If you know where she lived at any time in her life, that might help find her.
The names and dates of any spouse and children you know about.
If you know her parents names that would help, too.
Have fun searching and let us help.
