The legend begins with a pirate who heard a baby cry below decks and chose, against every professional instinct, not to kill anyone that morning. He gave the mother a bolt of green silk and asked that her daughter wear it at her wedding. She did. Mary Wilson grew up tall and red-haired in Londonderry, New Hampshire, married James Wallace in the green dress exactly as promised, outlived him, and retired to Henniker, where she is buried in the cemetery behind the town hall. Fragments of the silk still exist, on display in several towns across central New Hampshire. The pirate encounter was real. That much holds up.
What doesn’t hold up is everything else. The buried treasure, the captain following her to Henniker, the murder beneath the hearthstone — all of it was invented in 1917 by a Wisconsin man named Gus Roy who bought a house that had belonged to Mary’s son and turned it into a haunted attraction. He rented shovels to tourists digging for pirate gold in the yard. His ghost — a tall red-haired woman at the windows — became one of the most talked-about hauntings in New England. Lorraine Warren visited in 1949 and called it one of her first significant clairvoyant experiences. The house is still on Bear Hill Road, still private property, still marked with no-trespassing signs.
What remains accessible is the grave behind Henniker Town Hall — the stone findable with a few minutes of looking, the dates legible. A woman born at sea in the middle of a pirate raid who kept a stranger’s promise for the whole of her life. The ghost may be borrowed legend. The life was genuinely extraordinary.

What Others Have Experienced
A former Henniker High School student recalled driving up the dirt road to the house one Halloween in the 1950s on a dare. As the group reached for the door, the handle began to rattle back and forth on its own, convincing them the pirate’s ghost had arrived, before the owner finally opened up and gave them a tour of the gleaming maple-paneled attic.

Paranormal investigator Lorraine Warren, later known for the cases chronicled in The Conjuring films, visited the house in 1949 and said the experience was the first time she sensed she might be clairvoyant. The owner reportedly told her that sensitive visitors often had a hard time inside the place.

A traveler who tracked down both Mary’s actual gravestone and the privately owned house wrongly associated with her found the cemetery easy to reach, but the house itself was ringed with no-trespassing signs and missing the historical marker that once stood out front. Peering through the trees from the road, they couldn’t help wondering whether the legend’s real fabricator was the one still haunting the place.
