The pair both attended the school in the late 1920s and early 1930s when it was divided in two, in order to provide boarding facilities for students, such as Kathleen, who were from the country.
They also followed similar school careers, both passionate about music and studying commercial courses in order to secure jobs directly from school.
While they celebrated their 100th birthdays with the staff, their connection with the school is more often with the students. Ms Lawrence recently told her story to Year 11 literature students, including her great granddaughter Rebecca, while she has another great granddaughter Angela in Year 7 at the school.
In 2011, Ms Rudman attended the school’s 165th anniversary celebrations and regularly attends college events.
