Mary Dyer was my ancestor. The tales brought down through the ages were of how she originally was a puritan, they basically forced her out and after she went back to England to meet with people there, she converted to quakerism. She was taken back by the virtual hate and ruthlessness of the puritans back there and wanted nothing to do with them. It was said she met with Cromwell and her mind was changed after that meeting.
Apparently they tried repeatedly to banish her to no avail. The story about her baby is very sad also.
