For more than a decade, The Curse of Oak Island has thrived not only on mysterious artifacts buried beneath the island, but also on the lives of the people who help uncover them. Few off-screen topics have generated as much curiosity among fans as the long-running rumor linking Alex Lagina — son of series co-leader Marty Lagina — and archaeologist Miriam Amirault. The speculation intensified during the show’s later seasons, eventually sparking theories ranging from secret dating to a private wedding.

But as Season 16 unfolds and the Fellowship expands its scientific approach, it’s worth separating fact from fiction — and exploring how these two popular cast members may still shape Oak Island’s future, each in their own way.

A Rumor That Outgrew Its Origins

The chatter began in 2020, when Miriam Amirault first appeared in Season 8. She joined Oak Island’s archaeological efforts as part of Dr. Aaron Taylor’s team — cheerful, capable, and immediately memorable. Her on-screen presence with Alex, who often assisted with site work and artifact transport, was enough to generate an online whisper network. Fans pointed to their professional chemistry and occasional shared scenes as evidence of something more.

The reality, however, is far more straightforward.
There was never a relationship, and there was certainly no marriage.

Neither Alex nor Miriam ever acknowledged the romantic rumors, and production sources never suggested anything beyond a respectful working relationship. In the world of Oak Island fandom, however, silence often amplifies curiosity.

The Truth About Alex Lagina’s Marriage

In early 2024, the speculation finally came to rest: Alex Lagina married Katherine Sneed, a Michigan-based corporate communications specialist. The ceremony, held privately and attended by close friends and family, became public only after guests shared photos on Instagram and Reddit.

Sneed, who works at Hagerty — a global automotive and enthusiast brand — has no public social media, and Alex continues to maintain a deliberately low profile. For a family that has spent 11 seasons under intense documentary scrutiny, their choice to keep life offline has become a defining feature.

The Lagina brothers may run one of television’s most public treasure hunts, but their personal lives remain tightly guarded.

What Happened to Miriam Amirault?

Miriam’s trajectory on The Curse of Oak Island is quite different — and, in some ways, more mysterious.

After Season 8, she briefly returned for seven episodes in Season 10 (2022), only to depart once again without public explanation. In reality, this is not unusual. Oak Island’s archaeologists are hired professionals, not permanent cast members. Many work in academia, pursue graduate degrees, or juggle multiple excavation commitments.

Miriam, who studied at the University of New Brunswick, has expressed interest in forensic studies and higher academic work — which likely explains her absence far more than any dramatic narrative.

The young archaeologist also avoids social media entirely. Her low-profile lifestyle, combined with her sudden arrival and equally sudden departure, created the perfect conditions for fan speculation.

Will Miriam Return in Future Seasons?

While there is no official confirmation, several factors could signal a potential return:

1. Increased Archaeological Emphasis in Recent Seasons

The show has leaned more heavily into scientific analysis — from muon-scanning to dendrochronology — and archaeological oversight remains a requirement for all site work. As the Fellowship pushes deeper into areas like the Garden Shaft and Lot 5, additional archaeologists may be needed.

2. Audience Engagement

Miriam was a fan favorite from her first appearance. History Channel producers are well aware that her presence brings energy, approachability, and demographic diversity to the cast.

3. The Expanding Scope of the Dig

If drilling or excavation returns to areas requiring full archaeological documentation — particularly newly discovered tunnels or chambers — specialists like Miriam could be brought back on contract.

For now, her absence makes sense academically. But Oak Island’s cast history shows a pattern: once you’re part of the Fellowship, the door rarely closes completely.

How Alex Lagina Fits Into Oak Island’s Future

With his recent marriage and growing responsibilities behind the scenes, Alex’s presence on Season 16 may evolve. His background in engineering and project management has made him increasingly valuable as the dig becomes more technologically advanced.

Possible directions for Alex moving forward:

• Greater leadership roles, especially in operations previously handled by Craig Tester.

• Oversight of new remote drilling sites as the show expands beyond traditional Money Pit zones.

• Increased involvement in artifact analysis, given his experience working alongside archaeologists and metallurgists.

• More off-camera influence, particularly as the family continues to manage multiple enterprises.

While Alex remains one of the show’s most private cast members, he also represents the next generation of Oak Island leadership — something the series will eventually rely on as Rick and Marty approach their twelfth year of fieldwork.

What This Means for Oak Island Season 16 and Beyond

The fascination with Alex Lagina and Miriam Amirault says as much about the show’s success as it does about the individuals themselves. The Curse of Oak Island thrives because it blends mystery with humanity. Fans don’t just follow artifacts; they follow the people who uncover them.

And as the show moves into its next chapter, the dynamics around its cast — returning faces, absent experts, and the evolving roles of the Lagina family — will remain a central part of the narrative.

For now, the romance rumor can be officially buried deeper than the Money Pit. But the curiosity surrounding these two cast members isn’t going anywhere — especially as Oak Island continues to promise new leads, new discoveries, and new faces returning to the Fellowship.
