Chester Municipal Heritage Society is a volunteer-driven not-for-profit incorporated in 1981 and based in Chester, the Mahone Bay community on the mainland adjacent to Oak Island. The Society operates Chester Train Station, the Lordly House Museum, Maple Cottage (its research centre and the original first Chester municipal office), and Lordly Park. All members are volunteers; the Society has no paid staff and receives no operating government funding apart from successful grants.
The Society's archives are open to the general public and continue to accept and catalogue material from across the municipality. For Oak Island research, its holdings centre on two donated collections.
The D'Arcy O'Connor Oak Island Fonds, donated by author and journalist D'Arcy O'Connor, contains material gathered across more than thirty years of research on the Oak Island question. It comprises archival research notes, transcripts and recordings of interviews O'Connor conducted with treasure hunters, partners, witnesses, and observers from the 1960s through the early 2000s, on-site observations, correspondence, and original materials not held elsewhere.
The Les MacPhie research compilations, contributed by geotechnical engineer Les MacPhie (Master of Engineering, Nova Scotia Technical College, 1964), comprise structured PDFs assembled by MacPhie that consolidate the documentary record of Oak Island excavations from 1849 onward, with particular emphasis on geotechnical and archaeological conditions at the Money Pit, Smith's Cove, and the carbon-dating record. Individual MacPhie compilations are catalogued separately within this Research Archive.
The Society's online research portal at oakislandmystery.com provides folder-view and index-view access to digitized images of holdings within both fonds, plus additional materials catalogued by topic. Original or unwatermarked copies for academic, publication, or research use can be requested through the Society's contact, Danny Hennigar.

Why it matters
Chester Municipal Heritage Society is the principal archival repository for original Oak Island documentary material. The D'Arcy O'Connor Fonds preserves the field record of the Oak Island search across the second half of the twentieth century, including interview material with principal participants who are no longer living. The Les MacPhie compilations consolidate primary documents from the nineteenth and early-twentieth-century treasure companies into searchable structured PDFs that are themselves cited in subsequent Oak Island research. CMHS hosts both fonds and provides public access through oakislandmystery.com, the portal where many of the primary documents catalogued in this Research Archive are accessed.
