Emma Wedgwood, future wife of Charles Darwin, is born in Staffordshire, England. Both she and Charles Darwin are first cousins, sharing as a grandfather Josiah Wedgwood, who made a fortune making pottery.
Her family belongs to the Unitarian church and are non-conformists. As such, her religious beliefs develop through personal study rather than the simple adoption of received doctrines and teachings.
This makes her more receptive and tolerant of Charles Darwin's own skepticism towards religion and even theism. Over the course of their marriage they frequently discuss both Christianity and Darwin's evolving beliefs, which end at a strong agnostic position.
Emma never entirely shares Charles' views — her desire to hold on to belief in an afterlife creates more than a little bit of tension between them. Nevertheless, she values openness and honesty in their relationship far more than sharing particular beliefs or ideas.
