Norma Alice Cox was born in Bermuda to Gilbert and Constance Cox^[1] and grew up in Bermuda.^[2] Cox was a student of the Berkeley Institute and after her graduation she taught at Central School. In 1951, she enrolled at what was known as Hamilton Normal School, a training college for teachers located in Hamilton, Ontario.^[3] After completing her degree, she returned to teaching at Central School, taking summer courses offered in Bermuda by Queen's University courses to complete her education.^[4] On 11 April 1955, in Hamilton, Bermuda, Cox married Leonard Leroy Astwood.^[1] Cox-Astwood obtained a BA in psychology and literature from Queen's University and upon graduation enrolled at the University of Birmingham, where she earned a diploma in the psychology of childhood^[4]

After completing her basic tertiary education, Astwood taught English literature and mathematics at the Robert Crawford School and Prospect Girls School. In 1970, she enrolled for post-graduate study at Adelphi University in Garden City, New York, to pursue a doctoral degree in clinical psychology, subsequently completing her internship as a Clinical Fellow in Psychology at Harvard University Medical School from 1973 and 1974.^[5] Between 1974 and 1982, Astwood served the Bermuda Department of Education, as psychologist to schools.

For the first two years of the organization, Astwood served as coordinator keeping the momentum going until the group was formally organized in 1992,^[7] with the goal of increasing the number of women involved in politics throughout the Commonwealth of Nations.^[8] On 19 August, 1995, Astwood married Sir Frank Blackman, a Barbadian Secretary to the Cabinet and the island's first Ombudsman, on the patio of her home in Hamilton Parish^[9] and resigned her Senate Vice Presidency about a year thereafter.^[10]
