My grandmothers correct name is Lillian Mary Nolan, she had no step children, when she passed away she only had her 3 children James Donald Bourke, William Ronald Bourke and my mum Marie Ena Bourke/Sinnerton. The children stated as step children are from my grandfathers second marriage. They are my mum's half siblings. My mother was born in 1937 and passed away in 2005 at the age of 68.
