The Curse of Oak Island

Premise

The Curse of Oak Island follows brothers Marty and Rick Lagina, originally from Kingsford, Michigan, through their efforts to find the speculated treasure believed to be on Oak Island. The series discusses the history of the island, recent discoveries, theories, and earlier investigations of the site. Areas of interest include the "money pit", Borehole 10-X, Smith's Cove, Site 2, "Nolan's Cross", the "Hatch", and the "Swamp".

Notable finds

While wholesale treasure has not been found, some coins and artifacts have been dug up on the island over the years.

A Spanish copper coin, believed to be dated to the 17th century

A fake Roman sword

A supposed 12th-century manuscript

A small piece of material that may be a piece of an old book, a related bookbinder, and a piece of sheepskin parchment with markings that looked like medieval text on it

A human bone fragment of Middle Eastern ancestry

A lead cross with a square hole at the top from between 1200 and the 17th century in origin

A rhodolite garnet brooch of 400–500 years in age

A metal hinge

A claimed Roman era shipwreck, just off Oak Island, unauthenticated as of 2016

Ring bolts

Ox-shoes

A metal panel

A carved stone slab similar to some on the surface and one dug up in 1804

After centuries of excavation on the small island, some have speculated the show is a hoax and false news, while others speculate that if there ever was any treasure, it is already gone.

Personnel

Oak Island characters

Initially, the cast consisted of a core group including Rick, Marty, and Alex Lagina, Dan and Dave Blankenship, Craig Tester, Jack Begley, Dan Henskee, Charles Barkhouse, and Peter Fornetti. Over time, the Oak Island team has expanded. Some specialists who have been brought to the island for specific purposes, such as Terry Matheson, Laird Niven, and Gary Drayton, have joined the team as full-time members.

Rick Lagina: Brother of Marty, Rick is a retired postal worker who is the main driving force behind the project. At the age of eleven, he read an article about the Oak Island money pit in the January 1965 edition of Reader's Digest and got Marty, his younger brother, interested in the Oak Island mystery. In 2006, he and Marty purchased most of Oak Island.

Marty Lagina: Rick Lagina's younger brother who funds a large proportion of the project. He owns a vineyard in his home town of Traverse City, Michigan. He is a certified diver and is featured prominently in the spin-off The Curse of Civil War Gold.

Dan Blankenship (seasons 1–6): A treasure seeker on Oak Island for nearly 50 years, Dan was first attracted to the island after reading the same Reader's Digest article that Rick and Marty Lagina did. Dan was responsible for drilling borehole 10–X and had dived to the bottom of the 235-foot-deep (72 m) shaft, the deepest shaft on the island. In season 1, he was 90 years old and did not take an active part in the search but was often sought out by team members for his extensive knowledge. He died in 2019 at age 95, prior to the filming of season 7.

Dave Blankenship: Son of Dan Blankenship who has been helping his father on the island since the 1970s. Dave is one of only three permanent inhabitants of Oak Island. He is partially paralysed on the left side due to an industrial accident.

Craig Tester: The business partner of Marty Lagina, father of Drake Tester and stepfather of Jack Begley; he is an engineer.

Jack Begley: Stepson of Craig Tester, Jack tends to take on the dirtier jobs on the island, such as manually searching the spoils from various shafts, manual digging, and even walking through the swamp.

Recurring appearances

A number of individuals have made recurring appearances, usually when their expertise is called upon in association with the treasure hunt. They may appear many times in one season and then far more infrequently in other seasons or not at all, depending on what is required during the ongoing search.

Tony Sampson: A local resident and professional dive master. Like Charles Barkhouse, he is a freemason and is usually involved when there is a need to explore the waters around Oak Island or operate underwater in the island's triangle shaped swamp. However, he does appear at other times as well.

Brian Abbott (seasons 2–4): A sonar expert who is periodically called in to conduct sonar scans of boreholes on the island and who has also scanned the cavern at the bottom of borehole 10–X. Although he only appears in only a limited number of episodes, the narrator explains in The Curse of Civil War Gold that he has been helping the Oak Island team "for the past six years".

Dr. Christa Brosseau (seasons 3, 5–): A chemist at Saint Mary's University in Halifax who is often called on to analyse artifacts found on the island.

Mike Huntley (seasons 3–5): A local diver who dived borehole C–1 and has at times partnered with Tony Sampson and John Chatterton for other dives

Zena Halpern (seasons 4–5): A New York-based researcher who gives the team some ancient maps and has a theory that the Knights Templar were involved in the Oak Island mystery. When she dies in season 6, she bequeaths all of her research to Rick Lagina, which results in the Oak Island Research Centre being opened.

Andrew Folkins (seasons 4–5): The Irving Equipment project manager at the money pit.

Vanessa Lucido (seasons 4–): CEO of ROC Equipment, a company partnered with Irving Equipment to drive caissons into the money pit area.

Other appearances

In addition to regular and recurring cast members, there have been several visits by people who have a significant and sometimes intimate association with Oak Island.

Lee Lamb (seasons 1, 4–5): Daughter of treasure hunter Robert Restall who died in an accident in 1965 with his son and Lee's brother, Robert Jr, and two other men. When she visits the island, she usually brings something of significance with her.

Andrew Demont (season 1): The only survivor of the accident that killed Robert Restall and three others.

David MacDonald (season 3): The author who wrote the January 1965 Reader's Digest story that first attracted Dan Blankenship and Marty and Rick Lagina to Oak Island. He contributes a copy of the January 1965 Reader's Digest to a time capsule that is buried next to the Oak Island bicentennial memorial.

Joan, Jean and Joyce McGinnis (seasons 3–4): Three sisters who are direct descendants of Daniel McGinnis, the original discoverer of the money pit. On their first visit they show the team a small cross that is allegedly part of the original Oak Island treasure. Joyce died in 2017 and, in season 4, Joan and Jean return to the island to inter some of her ashes in the foundation of what was once the home of Daniel McGinnis.

Randall Sullivan (seasons 4, 6): An author and investigative journalist who once wrote an article about the Oak Island search for Rolling Stone magazine and is now writing a book about the treasure hunt. He works with the team in conducting research and compiling data offering his theories based on his own extensive research. In season 6, he presents Marty and Rick with the two signed copies of his book.

Rick Restall (season 5): Son of treasure hunter Robert Restall and brother of Lee Lamb, returns to the island in season 5 with his sister.

Background and production

Development

The Lagina brothers became fascinated with the island after reading the January 1965 issue of Reader's Digest magazine that features an article on the Restall family's work to investigate the so-called "money pit". Marty and Rick obtained a controlling interest in Oak Island Tours, which reportedly owns most of the island. The brothers were later approached by Prometheus Entertainment to do a reality show and engaged the assistance of father-and-son Dan and Dave Blankenship, permanent residents of the island who had likewise been searching for treasure since the 1960s.

Theories

The series explores various Oak Island theories and conjectures through conversations with independent researchers. Persons featured have included Zena Halpern discussing her theory about North African gold and sharing copies of a French map of the island that she claims is dated to 1347, J. Hutton Pulitzer discussing his theory of ancient mariner visitations, Petter Amundsen discussing his theory about codes hidden in Shakespearean literature and a secret project involving Sir Francis Bacon and the Rosicrucians, Daniel Ronnstam discussing his theory about the 90-foot stone being a dual cypher containing instructions on how to defeat the money pit flood tunnels with corn, authors Kathleen McGowen and Alen Butler discussing their theory involving the fabled Knights Templar treasure and an alleged relocation of historical religious artifacts to the island, and John O'Brien discussing his theory that the island contains treasures of the Aztec Empire. It has also been suggested by Zena Halpern, without evidence, that the Templars worshipped the Phoenician goddess Tanit.
