She was born in Tokyo, the tenth and youngest child of Hugh Waddell, a Presbyterian minister and missionary who was lecturing in the Imperial University. She spent the first eleven years of her life in Japan before her family returned to Belfast. Her mother died shortly afterwards, and her father remarried. Hugh Waddell himself died and left his younger children in the care of their stepmother. Following the marriage of her elder sister Meg, Helen was left at home to care for Mrs Waddell, whose health was deteriorating.
