The Timeline of Searchers is a chronological reference compiled by the Chester Municipal Heritage Society as part of its online research material at oakislandmystery.com. The document lists, in order, the principal individuals and corporate entities that have undertaken excavation, exploration, or research on Oak Island from the original 1795 discovery onward.
Entries include the Onslow Company (1804 to 1805); the Truro Syndicate (1849 to 1850); the Oak Island Association (1861 to 1864); the Oak Island Eldorado Company, also called the Halifax Company (1866 to 1867); the Oak Island Treasure Company (1893 to 1900); the Old Gold Salvage and Wrecking Company (1909); the Oak Island Salvage Company (1912); William Chappell's 1931 expedition; Gilbert Hedden (1936 to 1938); Erwin Hamilton (1938 to 1942); the Restall family (1959 to 1965); Robert Dunfield (1965 to 1966); the Triton Alliance period (1965 to 2005) under David Tobias and Dan Blankenship; Oak Island Tours Inc. and the modern Lagina-led search from 2006 onward.
For each entity, the timeline records the years of operation, the principal individuals involved, the methods and locations of work, and the key documented findings or claims. Internal cross-references point to the more detailed biographical and corporate records elsewhere on the CMHS portal.
What this source documents
Chronological listing of Oak Island searchers and companies from 1795 to the present; for each entity, the years of operation, principal individuals, methods of work, locations of activity, and documented findings; cross-references to biographical and corporate files elsewhere in the CMHS holdings.
Why it matters
The Timeline of Searchers provides a single reference orientation point for the 230-year search history. For research questions involving the sequence of expeditions, the relationships between successive companies, or the chronology of which features of the Money Pit and Smith's Cove were encountered or modified by which expedition, the timeline is the necessary first reference before drilling into individual records.
