1-Mary Lee 1654, technically Mary was “tried” (and I use the term loosely) and hanged at sea on the way to Maryland. When the ship arrived in St. Mary’s, the Council of Maryland investigated, at least to the point of hearing two depositions from men aboard. They testified that the ship Charity encountered storms, and the crew concluded Mary had caused the storms with witchcraft. The captain attempted to defuse the situation by offering to put Mary ashore in “Barmudoes [sic].” However, the winds prevented this option. The crew persisted, and Mary confessed (apparently under great duress). At this point she was hanged and dumped in the sea along with her belongings.

2-Elizabeth Richardson 1659, Elizabeth was also hanged at sea en route to Maryland. The case was brought before the Provincial Court of Maryland by complainant “John Washington of Westmerland [sic] County in Virginia” (George’s great-granddad). Washington charged Edward Prescott with causing “a Woman to bee [sic] Executed for a Witch” aboard his ship. Prescott did not deny the hanging, but laid the blame on a John Greene. Since Washington had failed to show up, Prescott was acquitted. This accusation may have been part of a nasty exchange between Washington & Prescott regarding a shipment of tobacco lost when a ship ran aground in the Potomac (but these subsequent events were no help to the unfortunate Elizabeth).

3-John Cowman 1674 (Calvert County), was the first person convicted of witchcraft on Maryland soil. He was sentenced to be hanged, but Governor Charles Calvert pardoned him. Calvert’s pardon included a condition that bordered on the sadistic. The pardon required Cowman to first be taken to the gallows and the noose placed around his neck.

4-Rebecca Fowler 1685 (Calvert County), was the first person both convicted of and executed for witchcraft in Maryland, no last-minute pardon would be forthcoming.

5-Virtue Violl 1715 (Talbot County), I couldn’t find a primary source on Virtue Violl. If the sources cited below are accurate, she was the last person in Maryland tried for witchcraft. She was acquitted.

6-Moll Dyer, 1697 (St. Mary’s County), I listed Moll Dyer last because her story does not involve a witch trial, and I believe the Moll Dyer story is folklore.
