"... the daughter of a Scottish Baptist minister and was five years older than her husband. Christina's enthusiasm for missions was kindled at the age of 14, after listening to the preaching of veteran southern African missionary Robert Moffat. She toiled as her husband's missionary co-worker and shared all the hardships of their travels throughout their marriage. They never had any children."
