Hugh Brewster was born on May 26, 1950 in London, United Kingdom. He is a son of Ormond Macmillan Brewster, a doctor, and Anne Brewster, a nurse and housewife.
Brewster has two elder brothers and a younger sister.
Six years after Brewster’s birth, the family moved to Georgetown, Ontario, Canada.
In the early childhood, the young Hugh dreamed to become a missionary. He adored reading, and swallowed about four or five books a week in a local library. Brewster loved the most the historical fiction books by Geoffrey Trease and Rosemary Sutcliffe.
When Hugh Brewster was thirteen-year-old boy, the family moved again – this time to Guelph, Ontario, Canada.
