Darwin's family background in religion

Charles Darwin was baptized on November 17, 1809  at St. Chand's Church in Shrewbury, England. His mother took him to Unitarian church until he was eight years of age. Unitarianism is a theology, which holds that God is only one person as appose to Trinity that views God as father, son, and holy spirit in one Godhead. Darwin's mother died when he was eight years old, but he continued to attend church regularly with his sister. One of his grandfathers, Erasmus Darwin, as well as his father were freethinkers. A freethinker has a philosophical viewpoint that holds that opinions should be based on science, logic, and reason as appose to authority, tradition, and dogma. Although, Darwin's father was a freethinker, but as a physician he avoided any social conflict with his Anglicans patrons. The extended family of Darwins and Wedgwoods was supported by the Whigs who were Unitarians. Whigs were a party in British parliment who contested with Tories. By looking at Darwin's family background, it can be assumed that the family were not as conservative as others at his time.
