Mary Dyer was one of many Puritans who emigrated to America to flee religious persecution from Charles I. She emigrated to Boston with her husband, William, in 1635. In the 1650s, she was introduced to the Quakers and became one. She was subsequently jailed and banished multiple times from Boston for attempting to spread her views. Defying those orders, she was eventually hanged on June 1, 1660 for proselytizing, which was against Puritan beliefs. Details on Mary’s story can be found here. Mary’s burial place is not confirmed. Some historians believe she was buried in Boston, where she was hanged, but most theorize she was interred at the family farm north of Newport, where her family resided (now Middletown). The family farm is now nonexistent, and is now the site of Naval Station Newport.
