"We have a possible dob as 11th July 1883 at ? King Edward Mother was Maggie Mclean no father mentioned"
Can you please share the name of 'possible'?
How did you arrive at 'possible', what is your connection to her?
Did 'possible' have children i.e. did she marry, who did she marry, where/when, where did she live/have family, do you have her on any census', where/when/with whom & where did she die?
Any info. from the above questions are needed to move forward.
