The term 'Group Living at Zero Latitude' can be summarized as PURITANS, an 8-letter word. The PURITANS were a group of English Protestants in the 16th and 17th centuries who sought to reform the Church of England. They believed that the Church of England was too similar to the Roman Catholic Church and wanted to purify it of its Catholic elements. They eventually left England and settled in the New World, where they established the Massachusetts Bay Colony. The PURITANS were known for their strict religious beliefs and their commitment to hard work and education.
