Debra - that was my worst thought when I started researching tonight, now I think you have decided it for me.
I was hoping marriage certificates would help me find her mother Mary Corbet nee Walsh.
As Margarets father was dead I was hoping to find that Mary Corbett had given permission for the first marriage. After all she was only 15, and an address of where they were living at that time.
I want to put a time line together of their places of residence after Richard Cobrbett (Mary Walsh's husband and Margaret Mary's father) died.
Mary Corbett - Margaret's mother died at 36 O'Grady Street.
Richard Corbett's - biography is getting more like "Home and Away" everytime I think of another path to research.
Thanks for your help, Cheers Ted
