Sovereign Grand Council Thirty-Third Degree Ne Plus Ultra
Of the Ancient Primitive Order of Hérédom 1807™
Declaration of Continuity:
The Ancient Primitive Order of Hérédom 1807™ derives from the Scottish High-Degree system transmitted from the Grand Orient of France through Joseph Cerneau, established in New York in 1807. This lineage was preserved through the Cerneau Supreme Council under Edmund B. Hays, and subsequently transmitted by Harry J. Seymour, Sovereign Grand Inspector General.
Following the Cerneau disruptions of the 1860s, Seymour continued the Rite with the approval of the Grand Orient de France, and transmitted the authority of the Rite to John Yarker, who perpetuated the tradition in Europe.
The documentation of this Cerneau-derived Scottish Rite working is preserved in the Fonds Maçonnique FM4-979 manuscript at the Bibliothèque nationale de France, which records the continuation of the Rite under the authority of Cerneau in New York in 1807.
Through the Yarker transmission the Rite continued through the Scandinavian line and into the present Sovereign Grand Council.
Thus the Ancient Primitive Order of Hérédom 1807™ stands as a continuation of the Cerneau Scottish Rite tradition descending from the Grand Orient of France and preserved through the Seymour–Yarker lineage.
The Sovereign Grand Council of the Thirty-Third Degree is the governing summit of the Ancient Primitive Order of Hérédom 1807™,
preserving the integrity of the degrees 4° through 33° in continuity with the French and French-American Antillean transmission.
