Single women in Puritan society had a very low social status and did not have much influence in society, but they were seen as very innocent, pure and credible people, since they were not married and had not been "corrupted". This is because, single women, in Puritan society, were considered children and therefore shared the same innocence, until they entered adulthood, where they would get married and leave the status of a child and, consequently, the status of incocence.
