In 1991 10-year-old Cornish schoolgirl, Abigail Wright, was unable to join the Girl Guides because she expressed a doubt about taking the oath, which included a commitment to pray to God – she was excluded for being honest. Humanists in Cornwall, concerned by Abigail's rejection, formed Cornwall Humanists to promote Humanism at grass-roots level. The group quickly expanded to include Devon and became known as South-West Humanists. Devon Humanists became a separate organisation in 1993.
